Question

factorise 2x⁴–x³–11x²–x+2=0​

Answer 1

Step-by-step explanation:

Dividing : 2x4-x3-11x2-x+2

("Dividend")

By : x+2 ("Divisor")

dividend 2x4 - x3 - 11x2 - x + 2

- divisor * 2x3 2x4 + 4x3

remainder - 5x3 - 11x2 - x + 2

- divisor * -5x2 - 5x3 - 10x2

remainder - x2 - x + 2

- divisor * -x1 - x2 - 2x

remainder x + 2

- divisor * x0 x + 2

remainder 0

Quotient : 2x3-5x2-x+1 Remainder: 0
