Question

Tolong yg bisa jawab!! pr buat besok

Answer 1

1. (2x+3) (3x-2)=6x2 -4x + 9x -6
=6x2 + 5x -6

2. (-4a+b) (4a+2b) = -16a2 -8ab + 4ab + 2b2
= -16a2 -4ab + 2b2

3.(x+y) (x-y) = x2 -xy + xy -y2
= x2 -y2

4.(x+y) (x+y) = x2 + xy + xy + y2
= x2 + 2xy + y2

5.(x-y) (x-y) = x2 -xy -xy -y2
= x2 -2xy -y2

semoga membantu ..
