Answer:

(u + 8)(u + 9)

Explanation:

Assuming you require to factorise the expression

u² + 17u + 72

Consider the factors of the constant term (+ 72) which sum to give the coefficient of the u- term (+ 17)

The factors are + 8 and + 9, since

8 × 9 = 72 and 8 + 9 = 17, then

u² + 17u + 72 = (u + 8)(u + 9) ← in factored form
