Answer:
x-=sqrt53
Step-by-step explanation:
(X-7)^2=(x^2-49)
add 49 to both sides
sqrt both sides
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
