Question

factorise A square -( b - C square)

Answer 1

${a}^{2} - ( {b - c)}^{2} \\ {x}^{2} - {y}^{2} \\ = (x + y)(x - y) \\ apply \: the \: identity \\( a - (b - c))(a + b - c) \\ = (a - b + c)(a + b - c)$

Answer 2

Answer:

a² - ( b-c)²

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

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

Step-by-step explanation:

since, x ² - y² = (x +y)(x -y)
