Question

x^2-(x-ab)(a+b)^2 factorise​

Answer 1

Answer:

x^2-ax-bx+ab

=x (x-a)-b (x-a)

=(x-b)(x-a)

Step-by-step explanation:

Answer 2

Answer:

x²-(x-ab) (a+b)²

••» x² - (x-ab) (a²+2ab+b²)

••» x² - [a²x + 2abx +b²x-a³b-2a²b²-ab³]

••» x²-a²x-2abx + b²x + a³b + 2a²b² +ab³

••» x²-a²x-abx-abx+b²x- a³b-a²b²-a²b²-ab³ 2

••» x²- abx -b²x - a²x +a³b +a²b²- abx +a²b² +ab³

••» x (x-ab-b²)-a² (x-ab-b²) - ab (x-ab-b²)

••» (x-ab-b²) (x-a²-ab)

••» [x-b(a+b)] [x-a(a+b)]
