You can
put this solution on YOUR website!If you mean a quadratic equation, the formula is:
x =
standard form of the quadratic equation is:
where:
a is the coefficient of the
term.
b is the coefficient of the x term.
c is the constant.
You solve for x.
The y value is 0 because you set the equation equal to 0.
Your roots are:
(x,y) = (x,0) where you replace x with the values you calculated for x.
The roots can be real or imaginary.
If the roots are real, the graph of the equation crosses the x-axis at y = 0.
If the roots are not real (contain an imaginary part which is a negative square root) then the graph of the equation will not cross the x-axis.
The quadratic formula works on all quadratic equations whether the roots are real or imaginary.
