Write a quadratic equation with -1/3 and 4 as its roots. Write the equation in standard form.
Since is a root, then , or is a factor
Since x = 4 is a root, then x - 4 = 0 is a factor
We can then say that: (3x + 1)(x - 4) = 0
After FOILing the binomials, we get: ------ Quadratic equation, in standard form
