exis [7]

Answer:

$\frac{2y^2+7y-7}{3-4y}$

Step-by-step explanation:

We are given

$\frac{7y+2y^2-7}{3-4y}$

we can rewrite it as

$\frac{2y^2+7y-7}{3-4y}$

we know that

2y^2+7y-7 can not be factored

so, we can not reduce this expression

because this is the only way to reduce it

so, we get reduced form as

$\frac{2y^2+7y-7}{3-4y}$
