Question

The area of a rectangle is represented by x^2-5x-24.if the width of the rectangle is represented by x-8 , express the length of the rectangle as a binomial.

Answer 1

You can find that by doing -24 / -8 = 3 so the second part will be x+3

( x + 3 )( x - 8 )

To see if it's true we can solve it 
x^2 + 3x - 8x - 24
x^2 - 5x -24
