this is okay thank you yeah sure so the first thing you do is you go to mode okay and there's an equation mode number five so i'll hit number five and then you want to pick quadratic equation so number three is ax squared the squared tells you it's quadratic so hit number three and then all it does is ask you for and so you can enter your and value so let's say for example is to you type to hit equals that stores to end for okay maybe 14 be and maybe 44 and hit equals and then once you've entered all three values hit equals again and it gives you your zeros so this is one of your zeros here but there should be two so you hit equals again and it will give you the other one and you can see it just changed from plus to minus there in the middle okay and that's all there is to it now to get back to the regular mode you go back to mode and you want number one which is computing mode so we were in equation mode number five you want to go back to computing mode to use it as usual okay that's it all right
