(q^2+11q+24)/(q^2-5q-24)
To simplify the expression (q^2+11q+24)/(q^2-5q-24), we can factor the numerator and denominator:
Numerator: q^2 + 11q + 24 = (q + 3)(q + 8)
Denominator: q^2 - 5q - 24 = (q - 8)(q + 3)
Now we can cancel out the common factors:
(q + 3)(q + 8)/(q - 8)(q + 3)
The (q + 3) factors cancel out, leaving:
(q + 8)/(q - 8) as the simplified expression.
What can this not equal
This expression (q^2+11q+24)/(q^2-5q-24) cannot equal zero. To find the values that make the expression undefined, we set the denominator equal to zero and solve for q:
q^2 - 5q - 24 = 0
Factoring the quadratic equation, we have:
(q - 8)(q + 3) = 0
Setting each factor equal to zero:
q - 8 = 0 or q + 3 = 0
Solving for q, we get:
q = 8 or q = -3
Therefore, the expression is undefined (cannot equal zero) for q = 8 and q = -3.
