$-\frac{3}{4}+x^2+9x-34=0$
Learn how to solve classify algebraic expressions problems step by step online. Find the break even points of the expression -3/4+x^29x+-34. Find the break even points of the polynomial -\frac{3}{4}+x^2+9x-34 by putting it in the form of an equation and then set it equal to zero. Subtract the values -\frac{3}{4} and -34. To find the roots of a polynomial of the form ax^2+bx+c we use the quadratic formula, where in this case a=1, b=9 and c=-\frac{139}{4}. Then substitute the values of the coefficients of the equation in the quadratic formula: \displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}. Simplifying.
