Question

Find the product of (2y+3)(2y-6)using sutable identity

Answer 1

Answer:

4y^2 - 6y - 18

Step-by-step explanation:

Use the identity (x + a)*(x + b) = x^2 + (a+b)*x + ab

Substitute values, you'll get answer.

Answer 2

Step-by-step explanation:

2y(2y-6) +3(2y-6)

4y^-12y + 6y-18

4y^-6y -18

2y^-3y-9

2y^-6y+3y-9

2y(y+3)+3(y-3)

(y-3) (2y+3)

y=3
