hope it helps u.....

Answer 2

Step-by-step explanation:

$\: \: \: \: 2 { x}^{2} - 9x + 10 = 0 \\ = > 2 {x}^{2} - 4x - 5x + 10 = 0 \\ = > 2x(x - 2) - 5(x - 2) = 0 \\ = > (x - 2)(2x - 5) = 0 \\ = > x - 2 = 0 \\ = > x = 2 \\ again \\ = > 2x - 5 = 0 \\ = > 2x = 5 \\ = > x = \frac{5}{2}$

Now x=2 and 5/2
