Solve x^2 + 13x + 12 = 0 by factoring.

x = -12, 1

x = -12, -1

x = 12, -1

x = 12, 1

What are the 2 characteristics we look for when trying to solve a quadratic equation?

A positive coefficient for x^2*x*2 & the equation set equal to 0.

There is no such thing as a quadratic equation

Factor and cancel

Distribute and combine like terms

Determine the values of a, b, and c for the quadratic equation:

4x^2 – 8x = 3

a = 4, b =-8, c =3

a = 4, b =8, c =-3

a = 4, b =-8, c =-3

a = -4, b =-8, c =-3

Solve the equation by completing the square: x^2 - 8x = 20.

x = 10 and x = 2

x = -10 and x = -2

x = 10 and x = -2

x = 10 and x = 2
