Here is a quadratic equation x^2 + 5x = 14
x^2 + 5x - 14 = 0 - Subtract 14 from both sides
(x + 7)(x - 2) = 0 - Factor
x + 7 = 0      x - 2 = 0  - Set each factor equal to 0
x = -7           x = 2  - solve each piece

If the constant is easy to find factors of then use the factoring method
If the constant is difficult and you have a graphing calculator, then graph
If no graphing calculator then use the quadratic formula

2. Consider the numbers 4/13 and 3/10 .
Alborosie
Set the denominators equal to each other. 4/13 becomes 40/130 and 3/10 becomes 39/130. Therefore, 3/10 is slightly less. A number in between would be 39.5/130 which is equivalent to 79/260
