Question

2y²+7y+5 ; 3y+9;3y²-4y-3 Add the given polynomial.

Answer 1

$\textbf{Answer :}$

The given polynomials are

(2y² + 7y + 5), (3y + 9) and (3y² - 4y - 3)

So, the required sum be

= (2y² + 7y + 5) + (3y + 9) + (3y² - 4y - 3)

= 2y² + 7y + 5 + 3y + 9 + 3y² - 4y - 3

= (2 + 3) y² + (7 + 3 - 4) y + (5 + 9 - 3)

= $\bold{5y^{2} + 6y + 11}$

Answer 2

Heya!!
Here is the solution to your question:-
=>The question says that we have to add three polynomials that are
$2 {y}^{2} + 7y + 5$
,
$3y + 9$
,and
$3 {y}^{2} - 4y - 3$
We have to find the sum of these three polynomials.
Let's do it:-
Step I: Write down these polynomials.
$2 {x}^{2} + 7y + 5 + 3y + 9 +3 {y}^{2} - 4y - 3$
Step II:Let's bring the like terms together:-
$2 {y}^{2} + 3 {y}^{2} + 7y + 3y - 4y + 5 + 9 - 3$
Step III: Add them.
$5 {y}^{2} + 6y + 11$

This is the required sum of the given polynomials.



Hope it helps you.
