Question 392535: how to solve quadratic system by graphng
Answer by richard1234(7193)   (Show Source):
You can put this solution on YOUR website! Just graph the quadratic equation. If it meets the x-intercept twice, it has two real roots; if it meets it once, then one double root, and if it doesn't touch the x-axis, then its roots are complex. However graphing doesn't always ensure very accurate roots of a quadratic or any other equation.
