Question

= c. Subtract i. 3x2-6xy+4y2 from 2xy-2x2-5y2
$3x^{2} - 6xy + 4y {}^{2} from \: 2xy - 2 {x}^{2} - 5 {y}^{2}$
pls solve
​

Answer 1

Answer:

Let q should be subtracted.

Then according to question,

3x

2

−4y

2

+5xy+20−q=−x

2

−y

2

+6xy+20

⇒q=3x

2

−4y

2

+5xy+20−(−x

2

−y

2

+6xy+20)

⇒q=3x

2

−4y

2

+5xy+20+x

2

+y

2

−6xy−20

⇒q=3x

2

+x

2

−4y

2

+y

2

+5xy−6xy+20−20

⇒q=4x

2

−3y

2

−xy+0

Hence, 4x

2

−3y

2

−xy should be subtracted
