Ax^2 + Bx + C = 0
x^2 +( b/a)x = -(c/a)
1. 1. x^2 +(b/a) + (b/a)^2 = (b/2a)^2 – (c/a)
2. 2, (x + (b/2a)^2) = (b/2a)^2 – (c/a)
3. 3. x +(b/2a) = + or - (b^2/4a^2)-(c/a)
4. 4. x = + or - Square Root b^2/4a^2 – c/a
5. 5. x = -b/2a + or - Square Root b^2-4ac/4a^2
6. 6. x = -b/2a + or - Square Root b^2-4ac/2a
7. 7. x = -b + or - Square Root b^2 – 4ac/2a
