**Cubic equations University of Sheffield**

15/10/1997 · What I want to know is the x intercepts. I know at least one must exist, but since I can't factor x^3-2x^2+4x-5 = 0 by grouping or Rational zero test, I don't know what to do. (I don't want to use my graphing calculator and trace it).... Finding the intercepts of an equation Finding the intercepts of an equation makes it easier to sketch the graph of the equation. The graph of some functions can have one intercept, more than one intercept or no intercepts.

Find the equation of a cubic relationship given that the graph has only two x intercepts, one at point (3,0) and the other at (-1,0). It is also known that the graph passes through the point (4,-10) and has a y-intercept of (0,-18)

## How To Find X Intercepts Of A Cubic Equation

### So the solutions for this equation are x=7/2;-4. 3.find the vertex of f(x)=3x^2-6x+8. vertex: the value of y that does not repeat. To get this, plug in a few consecutive values of x and see which one does not repeat an answer.

- I have tried substituting in the two points (-4,0) and (0,28) and solving simultaneously for b and c with no success, and the book gives two separate but equally correct solutions for b and c that satisfy the equation.
- To remove the radical on the left side of the equation, cube both sides of the equation. Simplify the left side of the equation . Simplify the right side of the equation .
