For this case we must simplify the following expression:


\frac {y ^ 2 + 7y + 6} {6y ^ 2-6}

We factor the numerator, looking for two numbers that when multiplied by 6 and when added together give 7. These numbers are +6 and +1.

Then, rewriting the expression:


\frac {(y + 6) (y + 1)} {6 (y ^ 2-1)} =

We rewrite the denominator:


\frac {(y + 6) (y + 1)} {6 (y + 1) (y-1)} =

We simplify similar terms:


\frac {(y + 6)} {6 (y-1)}

Answer:


\frac {(y + 6)} {6 (y-1)}

Answer:


(y + 6)/(6(y - 1))

Explanation:

The given expression is


\frac{ {y}^(2) + 7y + 6}{6 {y}^(2) - 6}

The numerator is a quadratic trinomial and the denominator is different of two squares when 6 is factored.

We factor both the numerator and the denominator to obtain;


( (y + 6)(y + 1) )/(6(y - 1)(y + 1))

Cancel out the common factors to get:


(y + 6)/(6(y - 1))

This is the simplest form since, we cannot simplify this further.
