Question

divide 5x³+x⁴+32 x+88 by x+2​

Answer 1

Answer:

If you use the long division to divide (4x³+ax²+2x-3) by (x - 2), you get:

The remainder R1 = 4a + 33 … (1)

If you use the long division to divide (x³ + 3x²-2x²+a) by (x - 2), you get:

The remainder R2 = a + 12 … (2)

Since R1 = R2, then 4a + 33 = a + 12 and a = -7
