Question

x²-x(a+2b)+2ab. factorise ​

Answer 1

Answer:

x²-x(a+2b)+2ab

=>x²-ax-2bx+2ab [:• MULTIPLYING (-x) WITH (a+2b)]

=>x(x-a)-2b(x-a) [:• TAKING x common in x²-ax and -2b in -2bx+2ab]

=>(x-a)(x-2b) [:• TAKING (x-a) COMMON]

=>x-a=0 ; =>x-2b=0

=>x=a ; =>x=2b

Answer 2

Step-by-step explanation:

x^2-x(a+2b)+2ab x^2-xa-2bx+2ab x(x-a)-2b(x-a). (x-a)(x-2b)
