11-74.

Multiply each expression below using generic rectangles.

1. $\left(4x − 1\right)\left(3x + 2\right)$

Draw the generic rectangle.

Place the two factors on the sides of the generic rectangle as dimensions.

Multiply the dimensions to find the area of each small rectangle.

$12x^{2} + 5x − 2$
1. $\left(m + 1\right)\left(3m − 2\right)$
$3m^{2} + m − 2$
1. $\left(k − 4\right)\left(6 − 5k\right)$
