Question

factorise:x2+2ax-b2-2ab​

Answer 1

Answer:

Step-by-step explanation:

x square - b square + 2ax - 2ab

[x - b] [x + b]  +  2a [x - b]

[x - b] [x + b + 2a]

Answer 2

Answer:

Step-by-step explanation:

Given quadratic expression x²+2ax-b²-2ab

= x²+2ax-b(b+2a)

Splitting the middle term, we get

= x² -bx +(b+2a)x - b(b+2a)

= x(x-b)+ (b+2a)(x-b)

= (x-b)[ x+(b+2a)]

= (x-b)(x+b+2a)
