"Relate the solutions of a system of a linear and a nonlinear equation in two variables to the graphs of the equations in the system."
What you'll learn
- Determine whether a quadratic equation has two, one or no real solutions from the sign of $b^2 - 4ac$, without solving it
- Explain the classification from the $\pm\sqrt{\phantom{x}}$ term in the quadratic formula
- Find every value of an unknown coefficient that gives a stated number of real solutions
- Translate a condition stated in words or about a graph's $x$-intercepts into a condition on the discriminant
