Question

2(3y 2 +2)(y 2 −2y+1) for y=−2​

Answer 1

Answer:

252 is the answer.

Step-by-step explanation:

Let the expression 2( 3y² + 2 )( y² - 2y +1 ) = a

Given y = -2

Substitute y in equation a

Then

2 ( 3 (-2)² +2 ) ( {-2}² - 2 ( - 2 ) + 1 )

= 2 ( 3 (4) +2 ) ( 4 +4 +1)

= 2 ( 12 +2 ) ( 9)

=2 (14) (9)

= 28 (9)

= 252

So 252 is the answer.
