Question

factorise -completely
4u²+8 u to​

Answer 1

Given equation

$4u^{2} +8u$

Solving, we get

$4u^{2} +8u\\\\\bold { Taking \ 4 \ as \ common, \ we \ get,}\\\implies 4(u^{2} +2u)\\\bold { Taking \ u \ as \ common, \ we \ get,}\\\implies 4u(u+2)$

$\boxed{\boxed{\bold{Therefore, \ the \ factorised \ expression \ is \ 4u(u+2)}}}}}$
