Question

Divide x3+ 5x2 +2x-8 by x+2​

Answer 1

Answer:

$\frac{x3−5×2+2x−8}{x + 2}\\ = x3 - 5 \times 2 + 2x - 8\\ = 2x - 8\\ = x3 - 5 \times 2\\(x - 4).(2)\\(x2)\\x3 - 5 \times 2 + 2x - 8 \: (dividend)\\by \: x + 2 \: (divisor)\\dividend \: x3 - 5 \times 2 + 2x - 8 \: divisor \:{x}^{2} {x}^{3} + 2 \times 2 = remainder \: - 7 \times 2 + 2x - 8\\divisor \: - 7 \times 1 - 7 \times 2 - 14x = \: remainder \: 16x - 8 \: divisor \: 16 \times 0 \: \: 16 x + 32 = \: remainder \: - 40 \: \\ quotient \: x2 - 7 + 16 \\ = remainder \: - 40$
