What is the factored form of the polynomial x^2 + 7x + 10?
Steps
Concepts
Step 1: Look at the polynomial x^2 + 7x + 10. We need to find two numbers that multiply to the last number (10) and add up to the middle number (7).
Step 2: The two numbers that work are 5 and 2 because 5 * 2 = 10 and 5 + 2 = 7.
Step 3: Now we can write the polynomial in factored form using these two numbers. We write it as (x + 5)(x + 2).
