How to Solve Quadratic Equations
Quadratic equations polynomial equation in a single variable where the highest exponent of the variable is 2:
$$ax^2+bx+c=0$$
Identify the values of $$a$$, $$b$$, and c in the quadratic equation. The variable $$a$$ is the coefficient of the $$x^2$$ term, $$b$$ is the coefficient of the $$x$$ term, and $$c$$ is the constant. For the equation $$3x^2 -5x - 8 = 0$$, $$a = 3$$, $$b = -5$$, and $$c = -8$$.
x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}
