Two real roots
WebMar 26, 2016 · Descartes’s rule of signs says the number of positive roots is equal to changes in sign of f ( x ), or is less than that by an even number (so you keep subtracting 2 until you get either 1 or 0). Therefore, the previous f ( x) may have 2 or 0 positive roots. Negative real roots. For the number of negative real roots, find f (– x) and count ... WebThe discriminant is less than zero, so there are two real roots. The discriminant is less than zero, so there are two complex roots. A. 1. 3x = 0.5x2 x = -6 or x = 0 x = -4 or x = 3 x = -2 or x = 1.5 x = 0 or x = 6 2. 0 = 5x2 - 2x + 6. D. & C. Is the solution shown below correct?

WebA quadratic equation ax² + bx + c = 0 has no real roots when the discriminant of the equation is less than zero. Therefore, the equation has no real roots. Try This: (x² + 2)² - x² + 2x = 0 … WebThe two roots of our characteristic equation are actually the same number, r is equal to minus 2. So you could say we only have one solution, or one root, or a repeated root. However you want to say it, we only have one r that satisfies the characteristic equation. You might say, well that's fine.
