Question

Factorise ab^2+(a-1)(b-1)

Answer 1

SOLUTION ☺️

$= > ab {}^{2} + (a - 1)(b - 1) \\ \\ = > ab {}^{2} + ab - b </u></em></strong><strong><em><u>+</u></em></strong><strong><em><u>1 \\ \\ = > ab(b + 1) - 1(b + 1) \\ \\ = > (b + 1) \: (ab - 1)$

HOPE it helps ✔️

Answer 2

Step-by-step explanation:

$\begin{lgathered} ab {}^{2} + (a - 1)(b - 1) \\ \\ ab {}^{2} + ab - b +1 \\ \\ ab(b + 1) - 1(b + 1) \\ \\ (b + 1) \: (ab - 1)\end{lgathered}$
