a²- (b-c)²

= [a-(b-c)] [a+(b-c)]

= (a-b+c) (a+b-c)

Here we used the formula

x²-y² = (x+y)(x-y)

a²-(b-c)² = (a+b-c)(a-b+c) ANSWER

Explanation:

Factorising a²-(b-c)²

_______________________

we know the algebraic identity:

x^2-y^2=>(x+y)(x-y)

_______________________

=[a+(b-c)][a-(b-c)]

= (a+b-c)(a-b+c)

Therefore,a²-(b-c)² = (a+b-c)(a-b+c)

HOPE SO IT IS HELPFUL.. MARK ME AS BRAINLIEST..✌️❣️..
