Question

Factorisation of Algebraic Expression 1) Factors of x2 + xy - 2y2


in this format ​

Answer 1

Answer:

Step-by-step explanation:

apply  a-b = 1  , ab =2

factors of 2 are 1 and 2

now ,

x2 +xy ( 2-1) -2y2

= x2 +2xy -xy -2y2

= x( x+2y) -y(x+2y )  {taking common  factor}

(x+2y) (x-y).
