i have trouble factoring this equation any time x^2 has a number before it i get confused and don't know how to factor
how would you solve this
-3x^2+5x-2

• Math -

Find two factors for each end term (3,-1 or -3,1) and (2,-1 or -2,1).

Figure how they could be summed to get the middle term.

However, I could not do this. Do you have a typo?

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

The "x intercept" is where y = 0, which is where the curve crosses the x axis. Solve y = x^2+ 2x- 8 = 0 You can write that as y = (x+4) (x-2) = 0 There are two places where y = 0. The factored equation tells you where they are. how …
