Question

divide by the long division method x cube + 8 x square - 3 x minus 24 by X + 8​

Answer 1

x + 8 ) x³ + 8x² - 3x - 24 ( x² - 3

x³ + 8x²

0 - 3x + 24

- 3x + 24

0

Therefore,

Quotient = x² - 3

Remainder = 0

Verification:

Dividend = Divisor × Quotient + Remainder

→ x³ + 8x² - 3x - 24 = (x + 8)(x² - 3) + 0

→ x³ + 8x² - 3x - 24 = x(x² - 3) + 8(x² - 3)

→ x³ + 8x² - 3x - 24 = x³ - 3x + 8x² - 24

→ x³ + 8x² - 3x - 24 = x³ + 8x² - 3x - 24

LHS = RHS

Hence verified
