how do you factor a quadratic equation with only two terms?
for ex 36x^2 - 81 = 0
There are a few ways.
One way is to move the numeric term to the other side:
36x² - 81 = 0 Add 81 to both sides:
36x² = 81 Divide both sides by 36:
x² = 81/36 Find the square root of both sides; don't forget the ± sign:
x = ± 9/6 = ± 3/2
