Question

5) What should be added to 5x2 + 4xy + 3y2 so as to get the sum 8x² + 7xy + 5y2.
​

Answer 1

Answer:

for this we need to subtract the first equation from the second equation

Step-by-step explanation:

8x2 + 7xy + 5y2

-5x2 + 4xy + 3y2

- - -

-------------------------

3x2 + 3xy + 2y2

---------------------------

So the right answer is 3x2 + 3xy + 2y2 should be added to the first equation to get the sum 8x2 + 7xy + 5y2

Hope so the above answer will be helpful to u

Answer 2

Step-by-step explanation:

Let the added number be P,

A. T. Q.

5x^2+4xy+3y^2+(P)=8x^2+7xy+5y^2

P=8x^2+7xy+5y^2-(5x^2+4xy+3y^2)

P=8x^2-5x^2+7xy-4xy+5y^2-3y^2

P=3x^2+3xy+2y^2
