The area of a rectangle is x^2+3x-4 the width of the rectangle is x-1. determine the ratio of the area to the width

The ratio of the area to the width is equal to

Step-by-step explanation:

we know that

Completing the square

therefore

Find the ratio of the area to the width

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

i think asking google will you get the answer to that question
