Answer:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*x^3-(12*x^2-5*x-6)=0
Step by step solution :

:
Equation at the end of step 1
(4 • (x3)) - (((22•3x2) - 5x) - 6) = 0

:
22x3 - (12x2 - 5x - 6) = 0

Checking for a perfect cube
3.1 4x3-12x2+5x+6 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 4x3-12x2+5x+6
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 5x+6
Group 2: -12x2+4x3
Pull out from each group separately :
Group 1: (5x+6) • (1)
Group 2: (x-3) • (4x2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.
Polynomial Roots Calculator :
3.3 Find roots (zeroes) of : F(x) = 4x3-12x2+5x+6
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
