factorize : x^3 - 9x^3-12x + 20
Answers
Step-by-step explanation:
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2". 1 more similar replacement(s).(((x3) + 32x2) - 12x) - 20 = 0 2.1 x3+9x2-12x-20 is not a perfect cube2.1 x3+9x2-12x-20 is not a perfect cube2.2 Factoring: x3+9x2-12x-20
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -12x-20
Group 2: 9x2+x3
Pull out from each group separately :
Group 1: (3x+5) • (-4)
Group 2: (x+9) • (x2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.

2.3 Find roots (zeroes) of : F(x) = x3+9x2-12x-20
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 -20.
The factor(s) are:
of the Leading Coefficient : 1
of the Trailing Constant : 1 ,2 ,4 ,5 ,10 ,20
