Reduce 7y + 2y 2 - 7 by 3 - 4y.

NARA [144]

Answer:

D. $2y^2+11y-10$ .

Step-by-step explanation:

Given:

We need to reduce $7y+2y^2-7$ by $3-4y$

Solution:

To reduce the equation means we need to subtract the one equation from other.

First we will arrange the equation n proper format we get;

$2y^2+7y-7$ ⇒ equation 1

Also Arranging other equation we get;

$-4y+3$ ⇒ equation 2

Now we will subtract equation 2 from equation 1 we get;

$(2y^2+7y-7)-(-4y+3)$

Now Applying distributive property for the sign we get;

$2y^2+7y-7+4y-3$

Now Arranging the like terms we get;

$2y2+7y-+4y-7-3\\\\2y^2+11y-10$

Hence the reduce form of the given equation is $2y^2+11y-10$ .
