Question

Find all real solutions to

(x-7)^2=4

Answer 1

x = 9

x = 5

In order to find the answer we need to get rid of the square so we are going to square root it like this:

(x - 7)^2 = 4

x - 7 = 2

= plus or minus 2

First add and you'll get

x = 9

And then subtract and you'll get

x = 5

Answer 2

x-=sqrt53

Explanation:

(X-7)^2=(x^2-49)

add 49 to both sides

sqrt both sides
