Question

x
$Subtract \: x {}^{2} - 2xy + 5y {}^{2} - 4from4xy - 5x {}^{2} - y {}^{2} + 6$
​

Answer 1

Answer:

Hey this can be done by simple algebraic subtraction. Let me show

Step-by-step explanation:

First write down the expression

4xy - 5x² - y² + 6

x² - 2xy + 5y² -4

Now Rearrange these terms

-5x² - y² + 4xy + 6

x² + 5y² - 2xy - 4

In algebraic subtraction the signs will change i.e +ve to -ve and -ve to +ve

-5x² - y² + 4xy + 6

-x² - 5y² + 2xy + 4

Add the terms and you will get the answer

-6x² -6y² + 6xy + 10

This can be further simplified into

-6(x² -xy +y²) + 10

Hope this helps you =))
