Write a quadratic equation whose roots are 2 and -1, and whose leading coefficient is 4

( 4x - 8 ) ( x + 1 ) = 0

If you equate each bracket to 0, it's roots will be 2 and - 1. Also, if you expand it, you will see that it will have a 4 in front of x^2, which is the 'leading coefficient'.

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
