Radical!

[paris567]

hello, im doing this question = square root of 2x+ 4 = 6
my answer=
2x+4 = 36
2x=36-4
2x=32
x= 16

I'm just asking how to properly verify the question?

… how to properly verify the question?

Hi paris. You meant to ask how to verify the solution, yes?

Substitute x = 16 into the given equation, and then evaluate the left-hand side to see whether you have a true statement.

Here's a note about notation, for typing square roots using a keyboard. We use the following convention because it shows the radicand clearly. (The 'radicand' is the expression inside a radical symbol. In the given equation, the radicand is 2x+4.)

sqrt(2x + 4) = 6

?
