Factor as the product of two binomials. x 2 + 3 x − 4
1 answer:
Answer:
Step-by-step explanation:
Given:
The best way to write a polynomial with three terms as a product of binomials is to FACTOR!
The middle number is 3 and the last number is -4.
Factoring means we want something like
We need two numbers that...
ADD together to get 3 and
MULTIPLY together to get -4
Test the numbers -1 and 4:
These are the right numbers! Now, I can write them as factored binomials!
