Question Type the correct answer in each box.
Consider these quadratic expressions:
A. -3x2 + 11x - 3
B. 11x2 - x + 10
C. 4x2 + 27x - 28
D. -3x2 + 11x + 31
For each polynomial operation, write the letter that corresponds to the resulting expression from the list.
(5x2 + 2x + 1) + (6x2 – 3x + 9) is equivalent to expression
(-3x2 + 6x - 12) + (5x + 9) is equivalent to expression
(8x + 16) - (3x2 – 3x - 15) is equivalent to expression
(5x2 + 23% – 7) - (x2 - 4x + 21) is equivalent to expression
