Question

What should be taken away 10x²+4y²-17 to get 4x²-2y²+4​

Answer 1

Answer:

6x²+ 6y²- 13 taken away 10x²+4y²-17 to get 4x²-2y²+4​.

Step-by-step explanation:

If you take something away from someone, you remove it from them.

Means what number should we subtract to get a new number

If the number is a

If a is taken away 10x²+4y²-17 then we get 4x²-2y²+4​

(10x²+4y²-17) - a = (4x²-2y²+4)

a =(10x²+4y²-17) - (4x²-2y²+4)

Remove bracket

a =10x²+4y²-17 - 4x²+ 2y² -4

Rearrange similar terms

a = 10x² - 4x² +4y²+ 2y²-17-4

a =(10 -4)x² + (4+ 2) y² - (17 + 4)

= 6x²+ 6y²- 13

So, 6x²+ 6y²- 13 taken away 10x²+4y²-17 to get 4x²-2y²+4​.
