the quadratic equation is
if leading coefficient is , we have ; so, the quadratic equation is
if roots are and , we can use zero product rule to find equation:
...plug in given values for roots
....multiply
.......now multiply each coefficient by since given that leading coefficient is
check it on a graph:
