1. 13.1 Introduction to Quadratic Equations
Goal:
-write a quadratic in standard form
-solve quadratic equations

2. Important Info Quadratic Equation: it’s highest degree is x²
Standard Form: ax² +bx + c =0
If its in the form ax²+bx=0, just factor out a common factor
If its in the form ax² +bx +c =0 then use bottoms up
If it does not =0 then move everything to one side of the equation and set it = 0

3. Solving Quadratic Equations
Change equation to “Standard Form”
Ax2 + Bx + C = 0
Factor the equation (if possible)
(x + 5)(3x – 7) = 0
Let each factor = zero, and solve for “x”.

4. Solve: x2 – 4x = x - 6

5. Solve: x2 = 7x - 10

6. Solve: 3x2 – 2x = 0

7. Solve: 2x2 + 3x = 35

8. Solve: x2 + 7x – 18 = 0

9. Solve: 7x2 + 4x – 3 = 0

10. Solve: m2 + 4m - 21= 0
