Question

Find the product of (x + 5)(x − 5).

Answer 1

Answer:

The product of (x + 5)(x − 5) is $x^2-25$.

Step-by-step explanation:

The given expression is

$(x+5)(x-5)$

Using distributive property we get,

$x(x-5)+5(x-5)$

again using distributive property we get,

$x(x)+x(-5)+5(x)+5(-5)$

$x(x)-5x+5x-25$

Combining like terms.

$x^2+(-5x+5x)-25$

$x^2-25$

Therefore the product of (x + 5)(x − 5) is $x^2-25$.

Answer 2

You use the FOIL method for this problem. you should get X^2-25
