  1. The Quadratic Formula Gives the solutions/roots of the equation ax2 + bx + c = 0.

  2. What is the Quadratic Formula for? It gives the solutions/roots of a quadratic function.

  3. Ex) x²+8x+12 = 0 Factoring (x+2)(x+6)=0 x+2=0 x+6=0 -2 -2 -6 -6 x=-2 x=-6 Roots(x-intercepts) are -2 and -6 Ex) x²+8x–11 = 0 Cannot be factored since nothing multiplies to give you -11 and add to give you +8. Therefore…….. Quadratic Formula

  4. How would you solve the following quadratic functions? -3x² + 24 =0 -3x² + 24x =0

  5. 1st…… You must understand this symbol ±

  6. Let’s try some others. : )

  7. Let’s try some others. : )

  8. What is the Quadratic Formula Gives the solutions/roots of the equation ax2 + bx + c = 0. This must be a zero

  9. Helpful Hint You can graph the related quadratic function to see if your solutions are reasonable.
