Answer 1

Hola Mate!!

Your answer :-

$= > 5 {x}^{2} - 3x - 2 \\ \\ = > 5 {x}^{2} - 5x + 2x - 2 \\ \\ = > 5x \: (x - 1) + 2 \: (x - 1) \\ \\ = > (5x + 2) \: (x - 1) \: are \: the \: factors.\\ \\ = > a) \: 5x + 2 = 0 \\ \\ = > 5x = - 2 \\ \\ = > x = \frac{ - 2}{5} \\ \\ = > b) \: x - 1 = 0 \\ \\ = > x = 1$
