Answer 1

hello here is your answer by Sujeet yaduvanshi ☝☝☝☝☝☝



2x²+5x-3

2(-3)²+5(-3)-3

2*9-15-3

18-15-3


0



that's all

Answer 2

$2 {x}^{2} + 5x - 3 = 2 {x}^{2} + 6x - x - 3$
$= 0$
=>
$2x(x + 3) - (x + 3) = 0$
=>
$(2x + 1)(x - 3) = 0$
=>
$x = \: - 0.5 \: and \: - 3$
thus there are solutions of the equation . hope it helps you...
