To factor the quadratic expression x2 + 12x + 32, we need to find two numbers that multiply to the constant term (32) and add up to the linear coefficient (12).
We can list the pairs of factors of 32:
- 1 and 32
- 2 and 16
- 4 and 8
Among these pairs, the numbers 4 and 8 add up to 12. Hence, we can rewrite the quadratic expression using these factors:
x2 + 4x + 8x + 32
Now, we can group the terms:
(x2 + 4x) + (8x + 32)
Next, we factor out the common factors from each group:
x(x + 4) + 8(x + 4)
Now, we can factor out the common binomial factor (x + 4):
(x + 4)(x + 8)
To summarize, the factored form of the expression x2 + 12x + 32 is:
(x + 4)(x + 8).
