Question

Subtract these polynomials.

(2x²+2x+3)(x²+2x+1)=

A x² + 4x+2

B. +4

C. x² + 4x+4,

D. x² + 2

Answer 1

x²+2

Choice D

Explanation:

(2x²+2x+3)(x²+2x+1)

Subtract these, which means

• 2x²+2x+3-(x²+2x+1)
• 2x²+2x+3-x²-2x-1

Bringing like terms,

• 2x²-x²+2x-2x+3-1
• x²+0+2
• x²+2

Choice D
