What is the quotient?
exis [7]

The quotient is \frac{3(y-5)}{2}

Explanation:

The expression is \frac{2 y^{2}-6 y-20}{4 y+12} \div \frac{y^{2}+5 y+6}{3 y^{2}+18 y+27}

Now, reciprocal the term \frac{y^{2}+5 y+6}{3 y^{2}+18 y+27} and convert ÷ to ×

\frac{2 y^{2}-6 y-20}{4 y+12} \times \frac{3 y^{2}+18 y+27}{y^{2}+5 y+6}

Taking the common terms out, we get,

\frac{2\left(y^{2}-3 y-10\right)}{4(y+3)} \times \frac{3\left(y^{2}+6 y+9\right)}{y^{2}+5 y+6}

Factorizing each numerator and denominator, we get,

\frac{2(y-5)(y+2)}{4(y+3)} \times \frac{3(y+3)(y+3)}{(y+3)(y+2)}

Multiplying the terms, we have,

\frac{6(y-5)(y+2)(y+3)^{2}}{4(y+3)^{2}(y+2)}

Cancelling the common factors, we get,

\frac{3(y-5)}{2}

Thus, the quotient is \frac{3(y-5)}{2}
