Answer:

plz mark this as brainliest

Step-by-step explanation:

We solve the given product (x−1)(1−2x) as follows:

(x−1)(1−2x)=(x×1)+[x×(−2x)]+(−1×1)+[(−1)×(−2x)]

=x−2x

2

−1+2x

=−2x

2

+3x−1

From the above calculations, we observe that the coefficient of x

2

is −2 and coefficient of x is 3.

Hence, the coefficient of x is 3.

Answer 2

We solve the given product (x−1)(1−2x) as follows:

(x−1)(1−2x)=(x×1)+[x×(−2x)]+(−1×1)+[(−1)×(−2x)]

=x−2x2−1+2x

=−2x2+3x−1

From the above calculations, we observe that the coefficient of x2 is −2 and coefficient of x is 3.

Hence, the coefficient of x is 3.

Here the degree is 2.
