The polynomial x^2 + 13x + 40 can be factored as follows:

x^2 + 13x + 40

=> x^2 + 8x + 5x + 40

=> x(x + 8) + 5(x + 8)

=> (x + 5)(x + 8)

**The factorized form of x^2 + 13x + 40 is (x + 5)(x + 8)**

The polynomial x^2 + 13x + 40 can be factored as follows:

x^2 + 13x + 40

=> x^2 + 8x + 5x + 40

=> x(x + 8) + 5(x + 8)

=> (x + 5)(x + 8)

**The factorized form of x^2 + 13x + 40 is (x + 5)(x + 8)**
