Question

(3x - 2) square
( 2y+4) square

Answer 1

Answer:

1.9x^2 -12x +4

2. 4y^2 + 16y + 16

Step-by-step explanation:

1. (3x - 2)^2

(x-y)^2 = x^2 -2xy + y^2

(3x - 2)^2 = (3x)^2 - 2 x 3x x 2 + (2)^2

= 9x^2 - 12x + 4

2. (2y + 4)^2

(x + y )^2 = x^2 + 2xy + y^2

(2y + 4)^2 = (2y)^2 + 2 x 2y x 4 + (4)^2

= 4y^2 + 16y + 16
