Question 48549: What three techniques can be used to solve a quadratic equation? Demonstrate these techniques on the equation "12x^2 - 10x - 42 = 0". Answer by Nate(3500) (Show Source):
You can put this solution on YOUR website! 1.)Graphing (at most times, not very accurate)
2.)Factoring
3x - 7 = 0
3x = 7
x = 7/3 or 2 1/3
and
2x + 3 = 0
2x = -3
x = -3/2 or -1 1/2
3.)Completing the Square = +-
4.)Quadratic Formula
