Problem:
What is the factored form of x²-x-12?
a. (x-3)(x+4)
b. (x-4)(x-3)
c. (x+3)(x-4)
d. (x+3)(x+4)
Solution:
(x² + 3x) + (-4x - 12)
x(x + 3) - 4(x + 3)
(x + 3) (x - 4)
Answer:
(x + 3) (x - 4)
Answer:
3. What is the factored form of x²-x-12?
a. (x-3)(x+4)
b. (x-4)(x-3)
c. (x+3)(x-4)
d. (x+3)(x+4)
When you use FOIL METHOD it would be:
[tex](x + 3)(x - 4) \\ x {}^{2} + 3x - 4x - 12 \\ x {}^{2} - x - 12[/tex]
