Question 47789
i need help with this quadratic using the formula.. i did the work and my answer came out to be irrational is this true?
a=3x^2+
b=8x+
c=2
3x^2+8x+2=0
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}
{{{x = (-8 +- sqrt( 8^2-4*3*2 ))/(2*3) }}}
{{{x = (-8 +- sqrt( 64-24 ))/(6) }}}
{{{x = (-8 +- 2*sqrt(10))/(6) }}}
{{{x = (-4 +- sqrt(10))/(3) }}}
yes you are correct.the roots are irrational
