Question

Find the width of box in terms of c when volume equals 50x-2x^3 the length equals x+5 and the height =2x

Answer 1

The answer is down

Explanation:

divide x-4 into the volume polynomial to get

2x^2-3x -2. Factor that into

(2x+1)(x-2)

the volume cubic factors into 3 factors

(x-4)(2x+1)(x-2)

those 3 factors are the sides of the rectangular box with

width = (x-4) and

height and length =

(2x+1) and (x-2)
