The quadratic equation has two solutions since the degree of the equation is two and the solutions to the quadratic may be real or complex. For the determination of the nature of the roots of a quadratic, we have to calculate the value of the discrimin...
This also tells the number of roots and whether or not the roots are real or imaginary. What is the discriminant formula? The discriminant formula is d=b^2-4ac given the equation of the quadratic is f(x)=ax^2+bx+c. The formula derives from the quadratic formula. Moreover, the ...
the expression b2 − 4ac which is used to find out how many solutions exist for a quadratic equation of the general form ax2 + bx + c = 0 and which indicates that two real solutions exist when it is positive, one solution exists when it is equal to zero, and no solutions exist wh...
Discriminant Main Concept The expression is called the discriminant of the quadratic equation . From the discriminant, you can determine how many real solutions (roots) the equation has: Discriminant Value Number of corresponding distinct real solutions.

9x2 - 6x = -1 9x2 - 6x + 1 = 0 Substitute the values of a, b, and c into the discriminant and simplify. b2 - 4ac = (-6)2 - 4(9)(1) = 36 - 36 = 0The discriminant is 0. So the equation 9x2 - 6x = -1 has two identical real number solutions.All...
