COMPLETING THE SQUARE 2x^2 -4x+3=9 2. QUADRATIC FORMULA 2x^2+4x=0

jek_recluse [69]

X = 3 and x = -1 are the answers for both. They are exactly the same equation.

FOR COMPLETING THE SQUARE
Make in terms of ()^2 which you can do by adding numbers to both sides. Eventually it will look like this:
(2x - 1)^2 - 7 = 0
Add to both sides, take a square root and then solve.

USE THE QUADRATIC FORMULA
Be sure to solve for zero and be aware of negatives when plugging in.

The vertex is the lowest/highest point, depending on if the parabola opens upwards or downwards.

So because the vertex opens upwards, we are looking for the lowest point which is at (2,-3).
