expand 2(x+4)(x-4)

Solution

expand

2 (x + 4) (x - 4)

Solution

2 x^{2} - 32

Solution steps

2 (x + 4) (x - 4)

Expand

2 (x + 4) (x - 4) : 2 (x^{2} - 16)

= 2 (x^{2} - 16)

Apply the distributive law:

a (b - c) = ab - a c

2 (x^{2} - 16) = 2 x^{2} - 2 \cdot 16

= 2 x^{2} - 2 \cdot 16

Multiply the numbers:

2 \cdot 16 = 32

= 2 x^{2} - 32
