Question

Please help! What is the first step in solving the function below?

Answer 1

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow C.\:factor \:\: out \:\: 2x$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: 2 {x}^{3} - 18 {x}^{2} + 40x$

$\qquad \tt \rightarrow \: 2x(x {}^{2} ) - 2x(9x) + 2x(20)$

$\qquad \tt \rightarrow \: 2x( {x}^{2} - 9x + 20)$

Henceforth, The most efficient first step in factorising the given trinomial is to factor out 2x
