selesaikan persamaan 2x²+3x-2=0 dengan melengkapi persamaan kuadrat sempura

2x^2+3x-2= 0
(2x+(3/2))^2 -(9/4)-2=0
(2x+(3/2))^2 - (17/4) = 0
(2x+(3/2)^2 = 17/4
(2x+(3/2)) = +- √(17/4) - (3/2)
2x = +- √(17/4)-(3/2)
x = (+- √(17/4))-(3/2))/2
x1 = √(17/4))-(3/2))/2
x2= - √(17/4))-(3/2))/2

semoga membantu
