(3x + 5) = 0

x= - (5/3)

x - 1 = 0
x= 1

Hence, solution is x = -(5/3) or x=1

Explanation:

The question gives you an equation 3x^2 + 2x -5 = 0.

Hence to solve the equation, factorise.

3x^2 + 2x -5 = 0
(3x + 5)(x -1) = 0

The 2 factors of the equation are (3x + 2) and (x - 1).

With (3x + 5) = 0 and (x - 1) = 0
Solve for x to find the solutions.
