Liner equation. Care to help?

Question

3x^2 + 5x + c/5-3 = 0

Answer 1

Sry I can't answer it now ( no paper I'm on iPhone ) but my advice is 2 get the x on the 0 side and use that after as a plugin to calculate y.;)

Answer 2

ya

Answer 3

You want us to solve? Use the quadratic equation:

x = [-(5) +/- sqrt((5)^2 - 4(3)(c/5 - 3))] / [2(3)]

= [-5 +/- sqrt(25 - 12(c/5 - 3)) / 6

= [-5 +/- sqrt(61 - (12/5)c)] / 6

That's about as simple as it goes.
