Question

Find the coefficient of x^2 in (x-1) (1-2x^2)​

Answer 1

Answer:

the coefficient of x² is 2

Step-by-step explanation:

(x-1) (1-2x^2) = x -2x³ - 1 + 2x²

so the coefficient of x² is 2

Answer 2

(x−1)(1−2x)

$\bold{=−2x^2+3x−1}$

A Coefficient is a constant number multiplied with a variable.

$\small \bold{Here \: as \: −2 \: is \: multiplied \: with \: x^2}.$

So it becomes the coefficient.
