Question

:- (3x – 7y + 1)2 - (2x - 9y - 8)?
​

Answer 1

Answer:

Answer:

=4x−5y+10

Step-by-step explanation:

Let's simplify step-by-step.

(3x−7y+1)(2)−(2x−9y−8)

Distribute the Negative Sign:

=(3x−7y+1)(2)+−1(2x−9y−8)

=(3x−7y+1)(2)+−1(2x)+−1(−9y)+(−1)(−8)

=(3x−7y+1)(2)+−2x+9y+8

Distribute:

=(3x)(2)+(−7y)(2)+(1)(2)+−2x+9y+8

=6x+−14y+2+−2x+9y+8

Combine Like Terms:

=6x+−14y+2+−2x+9y+8

=(6x+−2x)+(−14y+9y)+(2+8)

=4x+−5y+10!!
