Question

x³+ x²-3x - 5 is divisible by x find remainder plz fast​

Answer 1

Answer:

Let f(x) = -x3 + 3x2 - 3x + 5 and g(x) = -x2 + x - 1

We have:

Quotient, q(x) = x - 2 and remainder, r(x) = 3

Now,

Quotient Divisor + Remainder

= (x - 2)(-x2 + x - 1) + 3

= -x3 + x2 - x + 2x2 - 2x + 2 + 3

= -x3 + 3x2 - 3x + 5 = Dividend

Hence, the division algorithm is verified.
