o solution\.

Explanation:

Step1: Factor the quadratic equation

We need to find two numbers that multiply to - 7 and add up to - 6. The numbers are - 7 and 1. So, $u^{2}-6u - 7=(u - 7)(u+1)=0$.

Step2: Solve for u

Set each factor equal to zero.
If $u - 7=0$, then $u = 7$.
If $u + 1=0$, then $u=-1$.

Answer:

$u = 7,-1$
