Question

what is the coefficient of Y2 in the equation (3Y2-5)(4+4Y2)​

Answer 1

Answer:

-8

Step-by-step explanation:

[3y2-5][4+4y2]= 12y2- 20 +12y4 -20y2 =12y4 - 8y2 -20

Answer 2

Answer:

-8

Step-by-step explanation:

(3Y^2-4)(4+4Y^2)

=( 3Y^2)*(4) + (3y^2)*(4Y^2) -4*4-(4)*(4Y^2

=. -8y^2+12y^4-20

hence coefficient of Y^2 is -8.
