Find the factors such that the product of the factors is the trinomial 3x2-5x-2. This can be done by trial and error and checked using the FOIL method of simplifying polynomials.
(3x+1)(x-2)=0
Set each of the factors of the left-hand side of the equation equal to 0.
3x+1=0
Set each of the factors of the left-hand side of the equation equal to 0.
x-2=0
Since 1 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 1 from both sides.
3x=-1
Divide each term in the equation by 3.
3x/3=-1/3
Simplify the left-hand side of the equation by canceling the common terms.
x=-1/3
Since -2 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 2 to both sides.
