Answer: x = 5/2 or x = -1

Explanation:

2x² - 3x - 5 = 0

↓ You split the middle term into 2 terms

2x² - 5x + 2x - 5 = 0

↓ Then factor the first 2 terms and last two terms separately

x(2x - 5) + (2x - 5) = 0

↓ And you factor it out

(2x - 5)(x + 1) = 0

↓ Then you have to apply the zero product property

2x - 5 = 0 or x + 1 = 0

↓ Rearrange variables to the left side of the equation

2x = 5

↓ Then divide both sides of the equation by the coefficient of variable

x = 5/2

or -------------------------------------------------------------

x + 1 = 0

↓ Rearrange variables to the left side of the equation

x = -1
