4 Ways to Solve a Cubic Equation - wikiHow

Cubic equations arise in various other contexts. • Angle trisection and doubling the cube are two ancient problems of geometry that have been proved to not be solvable by straightedge and compass construction, because they are equivalent to solving a cubic equation. • Marden's theorem states that the foci of the Steiner inellipse of any triangle can be found by using the cubic function whose roots are the coordinates in the comple… WebSep 5, 2024 · The characteristic equation is. r2 + 10r + 25 = (r + 5)2 = 0. This has the repeated root of r = − 5. The general solution is. y = C1e − 5t + C2te − 5t. We use the initial values to determine the constants. 2 = C1e − 5 ( 0) + C2(0)e − 5 ( 0) = C1. Taking the derivative gives. y ′ = − 10e − 5t + C2(e − 5t − 5te − 5t). blacktown boys high school reviewWebSplitting (x^2 - 4x + 4) into its square roots results in this: (x - 2)(x - 2). The next step is to put all of that together. This gets us 3x(2x + 3)(x - 2)(x - 2) Since you can no longer factor this equation, it is in simplest form. That means we just leave it like that. The second example is a little different: x^3 - 4x^2 + 6x - 24. blacktown boys high school cap
