[tex] \large \tt Solution \: : [/tex]
[tex]\qquad \tt \rightarrow \: 2 {x}^{3} - 18 {x}^{2} + 40x[/tex]
[tex]\qquad \tt \rightarrow \: 2x(x {}^{2} ) - 2x(9x) + 2x(20)[/tex]
[tex]\qquad \tt \rightarrow \: 2x( {x}^{2} - 9x + 20)[/tex]
Henceforth, The most efficient first step in factorising the given trinomial is to factor out 2x
