Question 499194: x^2-97x-300
Answer by oberobic(2304)   (Show Source):
You can put this solution on YOUR website! Can you find two factors of 300 that are 97 apart?
If so, you can factor the quadratic equation.
Otherwise you have to use the quadratic formula.
.
3*100 comes to mind.
Since the coefficient of x is negative, then the signs will be -100 and +3.
.
(x -100)(x +3) = ??
.
Use FOIL.
.
(x -100)(x +3) = x^2 +3x -100x - 300
.
Collecting like terms, you have:
x^2 -97x - 300
.
That's what we wanted to find.
.
Answer:
x = 100, or x = -3
