Question 256525
Lets take one at a time:
a) solve 3x^2 - 5x -13 =0 what are the solution? x=?
step 1 - using quadratic, we get
{{{x = (5 +- sqrt(25-4*3*(-13) ))/6 }}}
{{{x = (5 +- sqrt(181))/6}}}
--

b) find the x-intercepts of f(x) = 3x^2-5x-13 
The x-intercepts are the same as solutions and roots.
{{{x = (5 +- sqrt(181))/6}}}
