$\frac{y^{y} - 4 y^{3}}{y^{2} + 3 y - 28}$

Step 1

Consider the form $x^{2} + b x + c$ . Find a pair of integers whose product is $c$ and whose sum is $b$ . In this case, whose product is $- 28$ and whose sum is $3$ .

$- 4, 7$

Step 2

Write the factored form using these integers.

$\frac{y^{y} - 4 y^{3}}{(y - 4) (y + 7)}$
