Question

The area of the rectangle shown is 2x^2-x-15 square units. What is the width of the rectangle?

Answer 1

The width is (2x + 5) or (x - 3)

Explanation:

The formula of an area of a rectangle:

`A=lw`

l - length

w - width

We have

`A=2x^2-x-15`

`2x^2-x-15=2x^2+5x-6x-15=x(2x+5)-3(2x+5)\\\\=(2x+5)(x-3)`
