How to solve two and three degree equations using 991 Ms Calculator

hello everyone welcome to civil engineering and stuff and in today's video we are going to learn how to solve 2 degree and 3 degree equations using 991 ms calculator so to solve this equation first of all we have to enter into the equation mode so to do that first of all we'll enter by clicking this mode three times so we'll click one two three and you can see here in the equation mode to enter into the equation mode we have to press one so we will press one now in the previous video we learned about how how to use the n1 image calculator if we have to solve the equation that contains two unknown variables in 300 variables by clicking these respective options now to enter into the degree mode we have to press the right button you can see here it is saying to if you want to go to degree you have to press this right button now here if our equation is 2 degree we will choose 2 if our equation is 3 degree we'll choose 3 now first of all in the first example we will use the 2 degree equation and the example that we are going to use is this one 5 square plus 6 plus 1 equal to 0 it's 2 degree equation so to enter into the 2 degree mode we have to press 2 so we will press so now we have to enter the value of and so here is five so we i'm going to enter five i'm going to enter five then i'll press equal to then the value of is six so i'll enter six i'll press equal to the value of is 1 and i'll press equal to and we have the solution so the value of is minus 2 sorry minus 0.2 and minus 1 right so these are the solution for this equation all right if you want to enter another values you can again by pressing equal to sign you can enter other values okay so this is how we solve the two degree equation now let us take another example for 3 degree equation and the example that we will be using is 2 square plus sorry 2 cube plus 3x square minus 11x minus 6 equal to 0. now right now the calculator is in 2 degree equation mode so to enter into the 3 degree equation mode we will again press mode 3 times one two three will again press one to enter into the equation mode we will press the right hand side button and then we will enter three to enter into the three degree equation mode now taking the example and putting the values 1 will be will be 3 will be minus 11 and will be minus then i'll press equal to sign and the value of is 2 comma minus 3 comma minus 0.5 since it is 3 degree equation so of course we are going to have 3 solutions and these are the solutions if you want to see again the solutions we can press the upward button okay so this is how we solve the two degree and three degree equation using nine and one ms calculator so hope the video was useful to you if so please do press the like button and share your views in the comment section do consider subscribing to the channel for more videos like this thank you for watching have nice day
