Question

The coefficient of x² in the product of (x-1) (1-2x) is​

Answer 1

Step-by-step explanation:

(X -1) ( 1 -2X) = X ( 1 -2X) -1 ( 1 -2X)

= X - 2 X^2 - 1 + 2X

= 2X^2 +3X -1

SO , COEFFICIENT OF X ^2 IS +2 .

Answer 2

Answer:

The coefficient of x² in the product of (x-1) (1-2x) is​

answer : -2

Step-by-step explanation:

for the coefficient of x² in ( x - 1 ) ( 1 - 2x ) we need to solve  this by multiply

x - 2 x² - 1 + 2x

= -2 x² + 3x -1

the given equation is algebric equation in this to find the  coefficient of any variable we need to multiply all the term to simplify

example

1. 3 x³ - 2x² + 5x + 9 in this equation variable of x³ is 3 , x² is -2 and x is 5.

2. 8 x² + 9x + 22 in this equation variable of x² is 8  and x  is 9
