Question

Subtract these polynomials.

(2x2 + 4x + 3) - (4x2 - 2x-3) =
O A. - 2x2 + 2x+0
O B. 6x2 + 6x + 6
O C. 6x2+2x+ 0
O D.-2x2+68+6

Answer 1

B. -2x2 + 6x + 6.

Explanation:

(2x2 + 4x + 3) - (4x2 - 2x-3) Distribute negative over the parentheses:

= 2x2 + 4x + 3 - 4x2 + 2x + 3

= 2x2 - 4x2 + 4x + 2x + 3 + 3

= -2x2 + 6x + 6.
