x(8x^2-10x+3)=0
factoring the trinomial in the parenthesis gives
x(4x-3)(2x-1)=0
there are three things multiplying on the left there. In order for this expression on the left to equal zero you need to set each of those three parts equal to zero and solve for x. This is because anything multiplied by 0 is zero, so there are three different values of x that could give us zero here.
x=0 is one of the solutions.
4x-3=0 and solve for x
2x-1=0 and solve for x
If you're having trouble factoring trinomials an easy method is the x-box method, heres a video on it. Look at more if you need more help understanding this type of factoring.

You can also use the AC method to factor trinomials. This works best when factoring quadratic terms. In this case, you can use it to factor (8x2 - 10x + 3).
