Solve first degree equations using calculator One hit to get the answer right away

hi everyone welcome back to my channel so for binomial or trinomial equations think that you already know how to solve it using your calculator so on your calculator you just go you just hit the combination buttons setup Alpha and then you try so if you solve for polynomials hit you and then choose the number of degrees so if you have secondary trinomial binomial is square plus BX plus equals zero you just type in the coefficient if you want to solve for trinomial do it again for three degrees set up Alpha two and then choose three so you have cubed plus square plus plus equals plus equals zero okay plus equals zero and you do the same thing for the force Power so this calculator you can do you can solve up to four three okay you can see two to fourths so to the fourth you can solve it as you can solve for to the fourth power but what about if you have case like just symbol one variable no meal monomial equation so how do you solve for it so let's go over this case so have equation 3x minus two equals one okay just take this as an example so when you solve for this one you add both sides add to both sides that gives you 3x equals three and then divide both sides by three to get and your final answer is equals one right very simple because just take this simple problem as as an example to show you how to do it on your calculator now let's transfer this into calculator so how do you solve this equation using your calculator well you type exactly the same what it looks on the paper into your calculator okay let me show you so type in have three -2 hit Alpha equals to get equals equal PSI 3x minus 2 equals one all right what do you do next you hit the combination buttons watch carefully shift solve and then give value for usually give it give 1 okay do not gives equals zero because it will cause an arrow so usually give one for so call equal one then his equal PSI so it gives you equal one okay that's the answer now let's move on another case so that's because this is simple case so you say that okay this symbol we can do it in my head what about when you see problem like this you can also do use calculator to software so if do it by hand first I'm gonna calculate everything on the left side first that gives me 0.02 and then take this Square calculate it got this number times and then divide both sides by this term So my answer is over nine or 0.888 so let's do it on your calculator to see if you get the same number time two okay equals zero one one five squared times all right sip solve give it one it goes twice 0.88 okay all right so those are the simple cases what about this one you said that okay can calculate this in my head can do this on my calculator using the way I've been using what about this one can you do it you may but don't think you would do it so all right just one hit on your calculator and that gives you an answer right away type exactly how it looks on the paper into your calculator again 30 divided by open parenthesis 10 plus 2X times times square root of 9.81 times remember you type exactly how it looks otherwise you will get an interact answer divided by 10 plus the 2 times 2 is 4 you can do simplification during the steps to minimize the thing you have to insert into the calculator equals one all right like again here is the important step ship solve and then give it one equals hit the equal side twice just wait for it all right real quickly got the answer of 0.91158 right that is your answer very quickly right this applied to any problem when you have only one variable okay and what about when you have two variables like square not the variable but two Roots squared cubed to the fourth and it appear something like this so let's say if put square here square can you use this method yes you can but it only gives you one variable okay and how you find the rest it only gives you one root and how do you find the rest all right so here is another example for two roots in three roots or so on so how do you solve these like share and subscribe to my channel so will show you in the next video stay tuned if you find the video is helpful feel free to give it like share and subscribe to my channel in order to receive the most current videos don't forget to hit the Bell so that you won't miss anything I'll see you next time
