Question 10640
To solve this problem one side of the equation must be = 0...

7.23x^2 + 11.67x + 19.49 = 32.35  | -32.35
7.23x^2 + 11.67x - 12.86 = 0


Then you can solve it with this formula:

{{{x=-p/2 +- sqrt( (p/2)^2-q ) }}} 

The unsquared x term is always p. (Here: p = 11.67x)
The term not involving any x is always q. (Here: q = -12.86)


{{{x=-11.67/2 +- sqrt( (11.67/2)^2+12.86) }}}
{{{x=-5.835 +- sqrt( 5.835^2+12.86) }}}
{{{x=-5.835 +- sqrt( 34.047225+12.86) }}}
{{{x=-5.835 +- sqrt( 46.907225) }}}
{{{x=-5.835 +- 6.848884946 }}}
x1 = 1.013884946 and x2 = -12.68388495


You're welcome. :-)
