Question

What should be subtracted from 2x² – y² + 3 to get - 4x²+ y² - 2.​
hi kindly don't write extra stuff in the answers or I will report you and pls give step by step explanation instead of straight up solution.
Thanks :D​

Answer 1

Answer:

according to the question. ( take the number as " x")

so, (2x^2 - y^2 +3) should be subtract from x to get 4x^2 + y^2 - 2

so, x - (2x^2 - y^2 + 3) = 4x^2 + y^2 - 2

here the symbols will be changed becoz it's multipling with symbol "-"

x= 4x^2 + y^2 - 2 + 2x^2 + y^2 - 3

x= 6x^2 + 2y^2 - 5

therefore, 6x^2 + 2y^2 - 5 should be subtracted

I hope it helped you ☺️
