The answer is #1

2x^2 +5x = 3

first you need to get the equation to = 0

so subtract 3 from both sides

2x^2 +5x -3 = 0

Factor

(2x - 1) (x -3)

Now solve for x

2x -1 = 0

add 1 to each side

2x = 1

divide both sides by 2

x = 1/2

x+3 = 0

subtract 3 from both sides

x = 3

2x² + 5x = 3 2x² + 5x - 3 = 0 (2x - 1)(x + 3) = 0 x = 1/2, -3 P.S. When you used the quadratic formula, was c = -3?
