expand 3(x+2)(x-2)

Solution

expand

3 (x + 2) (x - 2)

Solution

3 x^{2} - 12

Solution steps

3 (x + 2) (x - 2)

Expand

3 (x + 2) (x - 2) : 3 (x^{2} - 4)

= 3 (x^{2} - 4)

Apply the distributive law:

a (b - c) = ab - a c

3 (x^{2} - 4) = 3 x^{2} - 3 \cdot 4

= 3 x^{2} - 3 \cdot 4

Multiply the numbers:

3 \cdot 4 = 12

= 3 x^{2} - 12
