<span>(4x³-4+7x)-(2x³-x-8) = </span>4x³-4+7x<span> - </span>2x³ + x+8 = (4x³-2x³) + (7x+x) -4+8 =
= 2x³ + 8x +4
(4x³-4+7x)-(2x³-x-8) = 2x³ + 8x +4
For the first problem, the answer is B. For the second problem, the answer is A.
<span>b is greater than 4 or b is less than negative 5...is the answer</span>
