When given a quadratic equation in standard form where a b and c are all nonzero determine the value for the discriminant using the formula b2 4ac. Before you make a table first find the vertex of the quadratic equation. For example 5 a 12 b 1 c simplifies to a -b - c 5.
Ax 2 bx c 0.
You can calculate the discriminant b2 - 4ac first. Here a is the coefficient of which is generally called as leading coefficientb is the coefficient of x and the c is called as the constant term. The Standard Form We must know that a quadratic polynomial can be written as ax2 bxc. Positive there are 2 real solutions.
