SOLVING THE CUBIC AND QUARTIC
WebJul 27, 2024 · As mentioned before, the zeroes of the equation are called roots. To find zin Eq. 1, we first choose two auxiliary variables uand vsuch that u+ v= z, and substitute this expression in Eq. 1. A convenient grouping of the terms gives: Equation 2: Result of substituting u + v = z in Eq. 1. Now, uand v can have any values, as long as their sum is z. WebSummary. Quadratic Equation in Standard Form: ax 2 + bx + c = 0. Quadratic Equations can be factored. Quadratic Formula: x = −b ± √ (b2 − 4ac) 2a. When the Discriminant ( b2−4ac) is: positive, there are 2 real solutions. zero, there is one real solution. negative, there are 2 complex solutions. bitdefender for chromebook
9 Ways to Solve Quadratic Equations Using the Quadratic Formula - WikiHow
Web3. Solving cubic equations Now let us move on to the solution of cubic equations. Like a quadratic, a cubic should always be re-arranged into its standard form, in this case ax3 +bx2 +cx+d = 0 The equation x2 +4x− 1 = 6 x is a cubic, though it is not written in the standard form. We need to multiply through by x, giving us x3 +4x2 − x = 6 WebTo solve a cubic equation: Step 1: Re-arrange the equation to standard form. Step 2: Break it down to the product of linear factor and quadratic equation. Step 3: Then solve the quadratic equation. Here, Step 2 can be done by using a combination of the synthetic division method and the factor theorem. WebSolving Quadratics- Discriminate.
