A19-4 solve quadratic graphing

  1. 1. Solving Quadratics by Graphing<br />Algebra 1<br />
  2. 2. Solving by Graphing<br />There are several different ways to solve a quadratic equation. You have already learned to solve by taking square roots.<br />
  3. 3. Solving by Graphing<br />Quadratics cannot be solved the same way as linear functions because you have two x’s in one equation that are not like terms.<br />
  4. 4. Solving by Graphing<br />Linear equations have one solution.<br />Quadratic equations have two solutions.<br />
  5. 5.
  6. 6. Steps to Solve<br />Write the equation in standard form. ax2+bx+c=0<br />
  7. 7. Steps to Solve<br />Write the equation in standard form. ax2+bx+c=0<br />Make it into a function by replacing 0 with y.<br />
  8. 8. Steps to Solve<br />Write the equation in standard form. ax2+bx+c=0<br />Make it into a function by replacing 0 with y.<br />Find the vertex and points on both sides, then graph the function.<br />The solutions are the x-intercepts.<br />
