Solve this quadratics by factoring.
x2 + 2x = 3
x2 + 2x - 3 = 0
= (x-1)(x+3) = 0
x = 1 or x = 3
Is this quadratic formula?
Yes
What do you have to do to solve quadratics equation by taking square roots after step 1?
Isolate the squared term. Then, you have to take the square roots both sides. After that, solve the square roots to get x alone.
