Lesson+10.6+Notes

You must use the quadratic formula when you cannot complete the square (the “b” term doesn’t have a perfect square). The quadratic formula is formed by solving ax2 + bx + c for, for “x.” Remember the quadratic formula by the song (tune of "Pop Goes the Weasle!")
 * Solve Quadratic Equations by the Quadratic Formula**

"X equals negative "b" plus or minus the square root, of b squared minus 4ac all over 2a" //(Where "a" can’t be 0 and "b2-4ac" is greater than or equal to 0)// STEPS: 1) Get equation in standard form: ax2 + bx + c = 0 2) Substitute values into quadratic formula and simplify 3) Set up two equations; one for positive case and one for negative case. These are your solutions.
