Solving Quadratic Equations using the Quadratic Formula

Solving Quadratic Equations using the Quadratic Formula 1.11 - Solution

arrow_back Return to Solving Quadratic Equations using the Quadratic Formula

This exercise requires us to connect two main pieces of information about quadratics.

  1. The solutions, or zeros, on a graph are where the curve crosses the x-x\text{-}axis.
  2. The value of the discriminant tells us the number of the solutions.
First, let's identify the number of solutions for each graph.
Graph A\text{Graph A}

Graph B\text{Graph B}

Graph C\text{Graph C}

Now, let's connect the number of solutions to our graphs..

Graph Number of solutions
Graph A One Solution
Graph B Zero Solutions
Graph C Two Solutions
