Learn how to solve problems step by step online. Find the discriminant of the equation (6a^2)/12a+12b(2b^2)/12a12b. The discriminant (D) of a quadratic polynomial of the form ax^2+bx+c is calculated using the following formula, where a, b and c are the coefficients of the corresponding terms. From the equation, we see that a=6, b=\frac{2b^2}{12} and c=12b+12b. Replacing the values of a, b and c in the previous formula, we obtain. Multiply 4 times -6. The power of a quotient is equal to the quotient of the power of the numerator and denominator: \displaystyle\left(\frac{a}{b}\right)^n=\frac{a^n}{b^n}.
