Question

Factor completely x^2-48

Answer 1

Answer:
`(x-7)(x+7)`

Explanation:

To solve this problem you must apply the proccedure shown below;

- Make the equation equal to zero:

`x^(2)-49=0`

-Add 49 at both sides:

`x^(2)=49`

- Now, you must take the square root of both sides of the equation, then you obtain the following roots:

`x=√(49)\\x_1=7\\x_2=-7`

- Then you have:

`x^(2)-49=`
`(x-7)(x+7)`
