Question

Multiplying Binomials using Algebra Tiles
1. (y + 3) (2y-1)
2. (b-2) (3b +2)​

Answer 1

Step-by-step explanation:

1) y(2y-1)+3(2y-1)

2y^2-y+6y-3

2y^2+5y-3

2) b(3b+2)-2(3b+2)

3b^2+2b-6b-4

3b^2-4b-4

Answer 2

Step-by-step explanation:

1. (y+3) (2y-1)

=y(2y-1) + 3(2y-1)

=2y^2-y+6y-3

=2y^2+5y-3

2. (b-2) (3b+2)

=b(3b+2) -2(3b+2)

=3b^2+2b - 6b- 4

= 3b^2 - 4b - 4
