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%2F2+%2B-+sqrt%28+%28p%2F2%29%5E2-q+%29+
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%2F2+%2B-+sqrt%28+%2811.67%2F2%29%5E2%2B12.86%29+
x=-5.835+%2B-+sqrt%28+5.835%5E2%2B12.86%29+
x=-5.835+%2B-+sqrt%28+34.047225%2B12.86%29+
x=-5.835+%2B-+sqrt%28+46.907225%29+
x=-5.835+%2B-+6.848884946+
x1 = 1.013884946 and x2 = -12.68388495

You're welcome. :-)
