Question

If the area of a rectangle is x4 + 3x3 - 2x2 - 200 and the width is x + 5, find its length.

Answer 1

Answer:

Step-by-step explanation:

Area = 4x + 9 - 4 - 200

= 4x - 195

Since Area is lw, let the width be x + 5 and y be the unknown length.

Therefore (x + 5) (y) = 4x - 195

Answer 2

Answer:

x³ - 2x² + 8x - 40

Step-by-step explanation:

Area = length · width

(x⁴ + 3x³ - 2x² + 0x¹ - 200) = length · (x + 5)

length = (x⁴ + 3x³ - 2x² + 0x¹ - 200) ÷ (x + 5)
