Let's divide both sides by five
Sqrt(x+2) = 12/5
Lets raise both sides to the power two. We are doing this to get ride of square toot
x+ 2 = 144/25
We solve for x
x + 2 - 2 = 144/25
x = 144/25 - 50/25
x= 94/25

If 5%2Fsqrt%28x+%2B+2%29+=+12, then: x MUST BE > - 2, and highlight_green%28matrix%281%2C3%2C+x+=+263%2F144%2C+or%2C+-+1.82639%29%29
