Question

find the missing factor 2n^2(n-3)-4(n-3)=( )(n-3)

Answer 1

Factoring the common factor (n-3) from the terms on the left side, that left-side expression becomes
  (2n^2-4)(n-3)

We presume your missing factor is
  (2n^2-4)

★ FINDING MISSING FACTOR
---------------------------------------------

Given expression : -

LHS = 2n²(n - 3)- 4(n - 3)

RHS = (Missing factor)(n - 3)

Now,
---------

From LHS expression, we get,

2n²(n - 3) - 4(n - 3)

= (n - 3)(2n² - 4)

= 2n(n - 2)(n - 3)

Equalising this with RHS expression, we have,

Missing factor = 2n(n - 2)
