You can put this solution on YOUR website! Solve this problem using the quadratic formula please.
2x^2 + 5X - 3 = 0
here a = 2, b = 5 , c = -3
quadratic formula x1 = (-b- sqrt(b^2 - 4*a*c))/(2*a)
x2 = (-b+ sqrt(b^2 - 4*a*c))/(2*a)
x1 = (-5-sqrt(25+24))/4 = (-5-7)/4 = -3
x2 = (-5+sqrt(25+24))/4 = (-5+7)/4 = 1/2
