Solve 1(x+8)(x-8)

$$1 ( x + 8 ) ( x - 8 )$$

Evaluate

$$x^{2}-64$$

Solution Steps

Use the distributive property to multiply 1 by x+8.

$$\left(x+8\right)\left(x-8\right)$$

Multiplication can be transformed into difference of squares using the rule: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.

$$x^{2}-8^{2}$$

Calculate 8 to the power of 2 and get 64.

$$x^{2}-64$$

Expand

$$x^{2}-64$$
