Weiner · 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

Simone · Answer 2

x-=sqrt53

Step-by-step explanation:

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

add 49 to both sides

sqrt both sides
