1. Problem Description

We are asked to factor the quadratic expression x27x44x^2 - 7x - 44.

2. Solution Steps

To factor the quadratic x27x44x^2 - 7x - 44, we need to find two numbers that multiply to 44-44 and add up to 7-7.
Let the two numbers be aa and bb. Then we have:
a×b=44a \times b = -44
a+b=7a + b = -7
The factor pairs of 44-44 are:
1,441, -44
1,44-1, 44
2,222, -22
2,22-2, 22
4,114, -11
4,11-4, 11
The pair 44 and 11-11 satisfy the conditions since 4+(11)=74 + (-11) = -7 and 4×(11)=444 \times (-11) = -44.
Therefore, the factorization is (x+4)(x11)(x+4)(x-11).
x27x44=(x+4)(x11)x^2 - 7x - 44 = (x+4)(x-11).

3. Final Answer

(x+4)(x11)(x+4)(x-11)
