Question

Add 8x²+7xy-6y², 4x²-3xy +2y²​

Answer 1

Answer:

solution by adding  8x²+7xy-6y²,     4x²-3xy +2y²​  is $12x^2 + 4xy - 4y^2$

Step-by-step explanation:

our goal is to add  (8x²+7xy-6y²), (4x²-3xy +2y²​)

we need to add like terms

so (8x²+7xy-6y²)  +  (4x²-3xy +2y²​)  = (8x²+4x²) + (7xy -3xy) + (2y²-6y²)

⇒ $12x^2 + 4xy - 4y^2$

by adding  8x²+7xy-6y²,     4x²-3xy +2y²​ we get :

$12x^2 + 4xy - 4y^2$
