Find the Greatest Common Factor (GCF)
GCF = 2
Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
2(2x^2/2 + -2x/2 - 40/2)
Simplify each term in parentheses
2(x^2 - x - 20)
Factor x^2 - x - 20
= 2(x - 5)(x + 4)
Answer:
Step-by-step explanation:
The best way to start is to take out the common factor (2)
2(x^2 - x - 20)
What two numbers when multiplied together have a difference of 1 and multiply to 20?
The answer is 5 and 4,but you have to take the signs into consideration.
2(x - 5)(x + 4)
