Question

-7×2-3×y+10y2,8×y+2×2-11y2,8y2-3x2+6xy

​

Answer 1

Answer:

Answer :

i ) - 7x2 - 3xy + 10y2 , We can write our equation , As :

- 7x2 + 7xy - 10xy + 10y2

7xy + 10y2 - 7x2 - 10xy

y ( 7x + 10 y ) - x ( 7x + 10 y )

( 7x + 10 y ) ( y - x ) ( Ans )

ii ) 8xy + 2x2 - 11y2 , So

2x ( 4y - x ) - 11 y2 ( Ans )

Irreducible form

iii ) 8y2 - 3x2 + 6xy

8y2 - 3x ( x - 2y ) ( Ans )

Irreducible form
