Question

Add the polynomials 2x – 7 and 5x + 9.

Answer 1

Hii friend,

=> 2x - 7 + 5x + 9
=> ( 2x + 5x ) + ( - 7 + 9 )
=> 7x + 2

HOPE THIS HELPS YOU :)

Answer 2

Answer:

The required answer is $7x+2$.

Step-by-step explanation:

Steps to add polynomials:-

1) Arrange each of the polynomial from the highest degree of the polynomial to the lowest degree of the polynomial.

2) Group the like terms.

3) Now, add all the like terms.

Step 1 of 3

Consider the given polynomials as follows:

$2x-7$ and $5x+9$

Notice that both the polynomials are of degree 1 and is already arranged from the highest degree to the lowest degree of the polynomial.

Step 2 of 3

Group the like terms as follows:

⇒ $2x-7+5x+9$

⇒ $(2x+5x)+(-7+9)$

Step 3 of 3

Add the like terms as follows:

⇒ $7x+2$

Therefore, the required answer is $7x+2$.
