Question 280353
(-10x+11)+(4x^2+1/2x-14) 
-10x+11+4x^2+x/2-14
4x^2-10x+x/2+11-14
4x^2-9.5x-3
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} 
x=(9.5+-sqrt[-9.5^2-4*4*-3])/2*4
x=(9.5+-sqrt[90.25+48])/8
x=(9.5+-sqrt[138.25])/8
x=(9.5+-11.758)/8
x=(9.5+11.758)/8
x=21.258/8
x=2.657 ans
x=(9.5-11.758)/8
x=-2.258/8
x=-.282 ans.
