Answer:
Step-by-step explanation:
(1): “x2” was replaced by “x^2”. 1 more similar replacement(s).
Step by step solution :
STEP
1
:
Equation at the end of step 1
(((x3) + 32×2) + 29x) + 30 = 0
STEP
2
:
Checking for a perfect cube
2.1 x3+9×2+29x+30 is not a perfect cube
Trying to factor by pulling out :
2.2 Factoring: x3+9×2+29x+30
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 29x+30
Group 2: x3+9×2
Pull out from each group separately :
Group 1: (29x+30) • (1)
Group 2: (x+9) • (x2)
he groups have no common factor and can not be added up to form a multiplication.
Polynomial Roots Calculator :
2.3 Find roots (zeroes) of : F(x) = x3+9×2+29x+30
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
