What is this formula?
This is the standard formula.
This is the quadratic formula.
This is the square root formula.
This is the Pythagorean formula
What should you do first in solving this equation?
x2 + 6x - 13 = 3
Factor
Write down: a = 1, b = 6, c = -13
Subtract 3 from both sides.
Add 3 to both sides.
Identify the values of A, B, and C
10p2 + 7p - 20 = 0
A=1, B=7, C=-20
A=10, B=7, C=20
A=10, B=-7, C=-20
A=10, B=7, C=-20
Identify the values of A, B, and C
3m2 - 14 = 11m
A=3, B=-11, C=-14
A=3, B=-14, C=11
A=3, B=11, C=-14
A=3, B=-14, C=11
Solve using the Quadratic Formula
4v2 - 1v - 18 = 0
v = 2.25, -2
v = -2.25, 2
v = 2.24, -1.99
v = -2.24, 1.99
Solve using the Quadratic Formula
6p2 = 2p + 60
p = 3.33, -3
p = -3.33, 2
p = -5.98, 6.65
p = 5.98, -6.65
