One solution was found :
x ≓ 2.612887859
Step by step solution :
Step 1 :
Polynomial Roots Calculator :
1.1 Find roots (zeroes) of : F(x) = x3-3x-10
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 1 and the Trailing Constant is -10.
The factor(s) are:
of the Leading Coefficient : 1
of the Trailing Constant : 1 ,2 ,5 ,10
Let us test ....
P Q P/Q F(P/Q) Divisor
-1 1 -1.00 -8.00
-2 1 -2.00 -12.00
-5 1 -5.00 -120.00
-10 1 -10.00 -980.00
1 1 1.00 -12.00
2 1 2.00 -8.00
5 1 5.00 100.00
10 1 10.00 960.00
Polynomial Roots Calculator found no rational roots
Equation at the end of step 1 :
x3 - 3x - 10 = 0
Step 2 :
Cubic Equations :
2.1 Solve x3-3x-10 = 0
