Question

ADD:8x2 + 7xy – 6y2
, 4x2 – 3xy + 2y2 and -4x2 + xy – y
2

Answer 1

Answer:

We need to find the addition of :

To find the addition of these three equations we will have to add the like terms together and then write the final equation obtained.

We have three common terms in each equation: , xy, and

We will first add the   terms

we have: 8  + 4  - 4  = 8

Now we will add the xy terms

we have: 7xy - 3xy + xy = 5xy

Now we will add the  terms

we have: -6 + 2 -  = -5

Therefore the sum of these three equations will be: 8  + 5xy -5
