%28x%5E2%2B10x%2B16%29%2F%282x-10%29 Start with the given expression


2x-10=0 Set the denominator equal to zero. Remember, dividing by 0 is undefined.


2x=0%2B10Add 10 to both sides


2x=10 Combine like terms on the right side


x=%2810%29%2F%282%29 Divide both sides by 2 to isolate x



x=5 Divide


So x=5 makes the expression %28x%5E2%2B10x%2B16%29%2F%282x-10%29 undefined since it makes the denominator 2x-10 equal to zero.
