Type the correct answer in each box.
consider these quadratic expressions:
a. -3x2 + 11x β 3
b. 11x2 β x + 10
c. 4x2 + 27x β 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 β 3x + 9) is equivalent to expression
.
(-3x2 + 6x β 12) + (5x + 9) is equivalent to expression
.
(8x + 16) β (3x2 β 3x β 15) is equivalent to expression
.
(5x2 + 23x β 7) β (x2 β 4x + 21) is equivalent to expression
.
