Question

X3-8=0 Carson,s method solutions

Answer 1

Answer:

The Cardano's formula (named after Girolamo Cardano 1501-1576), which is similar to the perfect-square method to quadratic equations, is a standard way to find a real root of a cubic equation like

ax^3+bx^2+cx+d=0.

ax

3

+bx

2

+cx+d=0.

We can then find the other two roots (real or complex) by polynomial division and the quadratic formula. The solution has two steps. We first "depress" the cubic equation and then solve the depressed equation.

Answer 2

Answer:

x=2

Step-by-step explanation:

$x {3} = 8$

$= > x = \sqrt[3]{8}$

$= > x = \sqrt[3]{2}^{3}$

$= > x = 2$
