Question

solve square root of x+3 = 2

Answer 1

√x+3 = 2

First we should simplify the equation by squaring both sides:

x + 3 = 4

Isolate x by taking 3 off both sides:

x = 1

We should ALWAYS check that our answer is correct after working out the value of x. We can do this by substituting x into the original equation:

√x + 3 = 2

Turns into:

√1 + 3 = 2

Which turns into:

√4 = 2

Which is true, therefore we can confirm:

x = 1

Answer 2

Answer:

If you mean the square root of (x+3) here's the answer: x=1

Step-by-step explanation:

Pretend there's a square root over x+3:    (x+3)^2=2^2

First eliminate the square root by squaring both sides.

The square root is cancelled so you get

x+3=4

x=1
