Question

How can I solve 6 degrea equation?

Answer 1

Use The Rational Root Theorem to determine the possible rational roots (tricky name!). These can be tested using synthetic substitution/division to depress the function and determine a zero.

Descartes Rules of Signs provides the maximum number of positive or negative roots.

Answer 2

What is the equation?  Is it factorable?  

Answer 3

You can substitute the smallest degree with another factor let say x⁶ + x⁵ + x³ + 5 = 0 

 

Say x^3 = a therefore we have => a^3 + a^2 + a + 5 = 0 (substitution)
