Question

Find the x-intercepts (if any) for the graph of the quadratic function. give answers in exact form.

6x2 + 12x + 5 = 0

mathmale · Answer

The formula x=-b/(2a) is not applicable to finding the roots / zeros / x-intercepts of a polynomial; it's for the x-coordinate of the vertex.

To find the x-intercepts, set the given quadratic equal to 0 and solve the resulting quadratic equation.   Several methods are available for that purpose.
