Step-by-step solution

To solve the problem of factoring the quadratic expression f(x)=x2+12x+32 f(x) = x^2 + 12x + 32 , we will follow these steps:

  • Identify the pairs of integers whose product is 32.
  • Find the pair that also adds up to 12.
  • Use this pair to express the quadratic in its factored form.

Let's proceed with these steps:

Step 1: List all pairs of integers that multiply to 32:
1 and 32
2 and 16
4 and 8

Step 2: Determine which pair of these adds up to 12:
Checking each:
1+32=33 1 + 32 = 33
2+16=18 2 + 16 = 18
4+8=12 4 + 8 = 12

The pair 4 and 8 adds up to 12.

Step 3: Use this pair to factor the quadratic expression:
Thus, f(x)=(x+4)(x+8) f(x) = (x + 4)(x + 8) .

Therefore, the factored form of f(x)=x2+12x+32 f(x) = x^2 + 12x + 32 is (x+8)(x+4) (x + 8)(x + 4) .

Final Answer

(x+8)(x+4) (x+8)(x+4)
