Web24 jan. 2024 · We know \ ( {b^2} – 4ac\) determines whether the quadratic equation \ (a {x^2} + bx + c = 0\) has real roots or not, \ ( {b^2} – 4ac\) is known as the discriminant of these quadratic equations. Therefore, a quadratic equation \ (a {x^2} + bx + c = 0\) has Two distinct real roots, if \ ( {b^2} – 4ac > 0\) Webb2 −4ac 2a (1) and solving quadratic equations is something that mathematicians have been able to do since the time of the Babylonians. When b2 −4ac>0 then these two roots are real and distinct; graphically they are where the curve y= ax2 + bx+ ccuts the x-axis. When b2 −4ac=0then we have one real root and the curve just touches the x ...

In the Quadratic Formula, what does it mean if $b^2-4ac>0$, …
Webb) If b 2 − 4 a c = 0 b^2-4ac=0 b 2 − 4 a c = 0, then taking the square root of this number will give 0 0 0. Since in the Quadratic Formula, we take the positive and negative of the square root (which results to the same number, 0 0 0), then the expression of the Quadratic Formula will result to only one real number solution. WebIt was mentioned already that the discriminant of a polynomial is zero if and only if the polynomial has multiple roots (i.e. it has some factor of (x-a)^n for ...
