Square Root Function #3 Video
Steps to solve:
Step 1: Make sure that you have a perfect square equal
to a number performing algebra.
Step 2: Take the square root ( v) of both sides.
Step 3: Include the ± symbol on the numerical square
root (the one without the x).
Step 4: Simplify the square roots.
Step 5: Perform algebra to get x by itself.
Step 6: Write your answer as two separate solutions.
Do not include the + in your final answers. You will
need to calculate these because they are clearer and
show knowledge that you recognize the answer has
two solutions.
