Question

a3 b-a2 b +5ab-5b. factorize​

Answer 1

Answer:

we have to factorise the expression,

a³b - a²b + 5ab - 5b

solution : a³b - a²b + 5ab- 5b

= a²b × a - a²b × 1 + 5b × a - 5b × 1

= a²b(a - 1) + 5b(a - 1)

= (a²b + 5b)(a - 1)

= {a² × b + 5 × b} (a - 1)

= {b(a² + 5)}(a - 1)

= b(a² + 5)(a - 1)

Therefore the factorisation of a³b - a²b + 5ab - 5b is b(a² + 5)(a -1).
