expand (3a-1/4 b)2

Solution

expand

(3 a - \frac{1}{4} b) 2

Solution

\frac{12 a - b}{2}

Solution steps

(3 a - \frac{1}{4} b) \cdot 2

= 2 (3 a - \frac{1}{4} b)

Apply the distributive law:

a (b - c) = ab - a c

2 (3 a - \frac{1}{4} b) = 2 \cdot 3 a - 2 \cdot \frac{1}{4} b

= 2 \cdot 3 a - 2 \cdot \frac{1}{4} b

Simplify

2 \cdot 3 a - 2 \cdot \frac{1}{4} b : \frac{12 a - b}{2}

= \frac{12 a - b}{2}
