Questions & Step-by-Step Solutions
Factor the expression: x^2 + 7x + 10.
Steps
Concepts
Step 1: Identify the expression you want to factor, which is x^2 + 7x + 10.
Step 2: Look for two numbers that multiply to the constant term (10) and add up to the coefficient of the x term (7).
Step 3: List the pairs of numbers that multiply to 10: (1, 10) and (2, 5).
Step 4: Check which pair adds up to 7. The pair (2, 5) works because 2 + 5 = 7.
Step 5: Write the factored form using the numbers you found: (x + 2)(x + 5).
