A quadratic equation is a polynomial equation of the second
degree. The general form is ax2 + bx + c =
0.
Are you able to derive a quadratic equation when the roots don’t
have fractions? For example, if the roots of a quadratic equation are 3 and 4,
then you can derive the equation as follows:
1. (x-3)(x-4) = 0
2. x2 – 7x
+12 = 0
What
if one or more roots is a fraction? Well, the approach
is the same. If the roots are 3 and -3/2, then you can derive the equation as
follows:
1. (x-3)(x-(-3/2) = 0
2. x2 –
(3/2)x +(9/2) = 0
