Given f(x)=6x^47x^323x^2+14x+3, approximate each real zero as a decimal to the nearest tenth.

Since there are apparently no rational roots, and quartics are ridiculously hard to solve algebraically, I assume you are working on numerical methods. So, use any method of choice (Newton, bisection, etc.) to approximate the roots. Where do you get stuck?
