simplify (3x+4y)2

Solution

simplify

(3 x + 4 y) 2

6 x + 8 y

Solution steps

(3 x + 4 y) \cdot 2

= 2 (3 x + 4 y)

Apply the distributive law:

a (b + c) = ab + a c

2 (3 x + 4 y) = 2 \cdot 3 x + 2 \cdot 4 y

= 2 \cdot 3 x + 2 \cdot 4 y

Simplify

2 \cdot 3 x + 2 \cdot 4 y : 6 x + 8 y

= 6 x + 8 y
