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

Solution

expand

2 (x + 3) (x - 3)

Solution

2 x^{2} - 18

Solution steps

2 (x + 3) (x - 3)

Expand

2 (x + 3) (x - 3) : 2 (x^{2} - 9)

= 2 (x^{2} - 9)

Apply the distributive law:

a (b - c) = ab - a c

2 (x^{2} - 9) = 2 x^{2} - 2 \cdot 9

= 2 x^{2} - 2 \cdot 9

Multiply the numbers:

2 \cdot 9 = 18

= 2 x^{2} - 18
