Solving X3 4×0 Reddit Cubic Equation R Askmath

Cubic Equation Problem : R/askmath

Cubic Equation Problem : R/askmath If i have a cubic x³ bx² cx d, i can get the same coefficient for the x² term and the x term by doing (x c/b)³ multiplied by b²/3ac. but then i get different coefficients infront of the x³ term? is there any way to proceed with this method?. In fact the original equation is already an implicit formula. ps. if your algebra is correct you may still be able to use these to find a root by repeatedly applying one of them to a "guess" value of x.

Equation Solving Help : R/askmath Solving a cubic equation actually starts with that step of getting rid of the quadratic term, but there are more ugly steps necessary, and nobody basically does this by hand anymore. To do this you need to solve for a value z such that the transformed equation can be solved by simply completing the cube. completing the cube is possible as long as bt^2 = 3ct in the transformed equation x^3 btx^2 ctx dt = 0. I was told to solve the general form x^3 px q = 0 for any real p and q using this technique but i am stumped. As to how you'd actually go about solving this fortunately for us, this is a depressed cubic, so we can skip over eliminating the quadratic and focus on moving this into more favourable coordinates.

Cubics have a general formula just like quadratic equations. the formula itself is quite lengthy however, but it works every time. To solve a cubic equation, start by determining if your equation has a constant. if it doesn't, factor an x out and use the quadratic formula to solve the remaining quadratic equation. Solving x^3 4x=0 reddit r/askmath. By hit and trial find one factor of this equation. say f (2) = 2^3 3.2^2 6.2 1 = 8 12 12 1 = 8 1 = 7 f (2) = 7 clearly this isn't a root, you may try different values to get your answer. after you have found your factor say (x a) divide (x a) by f (x). you will get a quadratic.
