Question

factorise a²(b+c)-(b+c)²​

Answer 1

Answer:

Please mark me as brainiliest .

Step-by-step ---

a²(b+c)-(b+c)³

= (b+c)[a² - (b+c)²]

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

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

Answer 2

Answer:

$a^{2}(b+c)-(b+c)^{2}\\(a^{2}*b+a^{2} *c)-(a^{2}*b+a^{2}*c )^{2} \\(a^{2} b+a^{2}c)^{2} -(a^{2} b+a^{2} c)\\(a^{2}b+c)-(a^{2}b+c )\\0$
