If you are looking at a graph of a quadratic equation, how do you determine where the solutions are? When looking at the graph you would want to look at the x axis to see where two points cross. In addition you can also look to see if the graph has just one point that touches the z axis. Last the graph may never touch the x axis. The first option, the equation has two distinct, real roots. In the second option the equation has a repeated, real root. In the third option, the equation has a pair of complex roots, one of which is

Unformatted text preview: the complex conjugate of the other. However, you need to find the discriminate, and the terms inside the square root of the quadratic formula for + + = :-ax² bx c 0 b² 4ac . If the discriminant is positive, the equation has two real, distinct roots. If the discriminant is zero, the equation has two repeated roots. If it is negative, the equation has two complex conjugate roots....
