Question

A rectangle has an area of x^3 + 5x^2 + 5x – 2 square meters and a width of x + 2 meters. Find its length.

Answer 1

Answer: x^2 + 3x - 1.

Step-by-step explanation: We need to divide x^3 + 5x^2 +5x-2 by x+2. This is dividing polynomials. Divide each number by x and multiply the quotient by 2 and subtract the answer.
