Find the sum. (2a2 + ab + 2b) + (4a2 − 3ab + 9)

The sum is  

Step-by-step explanation:

Given two expression

and

We have to find the sum of above two expression.

Combining like terms we get

=

The sum is  

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
