Answer 1

Answer:

hope this is the answer..

Answer 2

Answer:

$2 {x}^{2} + 3x - 5 = 0 \\ 2 {x}^{2} - 2x + 5x - 5 = 0 \\ 2x(x - 1) + 5(x - 1) = 0 \\ (x - 1)(2x + 5) = 0 \\ x - 1 = 0 \: \: or \: \: 2x + 5 = 0 \\ x = 1 \: \: or \: \: 2x = - 5 \\ \large{ \boxed{x ={ \underline{ \underline {1}}} \: \: or \: \: x = { \underline{ \underline {\frac{ - 5}{2} }}}}}$
