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
