Or use Wolfram|Alpha
Using Wolfram Alpha, we get a = -104/253, b = 2080/253, c = 2496/253, d = 3328/253, e = 1508/253, f = 4056/253
I believe it's 5.
It's correct, thanks!!!
We can use Vieta's Formulas. Simplifying, we get \(2y^2-11y+4\) and by Vieta's, we get \(\frac{11}{2}\)
It's correct, thanks!!
