Okay then. Another question para usted.

I have trouble factoring quadratic equations wanna help?

For example, how would I factor 2x^2 - 16x + 4 = 0?

Use the almighty quadratic formula: (-b +/- (b^2 - 4ac) ^ (1/2)) / 2a

That is

a=2
b=-16
c=4

Then it's: (16+/- (256-32)^ (1/2)) / 4 = (16 +/- 14.96)/4 = approx 31/4 and approx 1/4

So it results= 2 (x-31/4) (x-1/4)
