Other Ways to Solve

Simplification or other simple results

Step by Step Solution

Step 1 :

Equation at the end of step 1 :

((((9•(x5))-(7•(x2)))+5x)-3)+((((2•(x4))+22x3)-6x)-8)

Step 2 :

Equation at the end of step 2 :

((((9•(x5))-(7•(x2)))+5x)-3)+(((2x4+22x3)-6x)-8)

Step 3 :

Equation at the end of step 3 :

((((9•(x5))-7x2)+5x)-3)+(2x4+4x3-6x-8)

Step 4 :

Equation at the end of step 4 :

(((32x5 - 7x2) + 5x) - 3) + (2x4 + 4x3 - 6x - 8)

Step 5 :

Trying to factor by pulling out :

5.1 Factoring: 9x5+2x4+4x3-7x2-x-11 Thoughtfully split the expression at hand into groups, each group having two terms :Group 1: 4x3-7x2 Group 2: 2x4+9x5 Group 3: -x-11 Pull out from each group separately :Group 1: (4x-7) • (x2)Group 2: (9x+2) • (x4)Group 3: (x+11) • (-1) Looking for common sub-expressions : Group 1: (4x-7) • (x2) Group 3: (x+11) • (-1) Group 2: (9x+2) • (x4)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 :

5.2 Find roots (zeroes) of : F(x) = 9x5+2x4+4x3-7x2-x-11Polynomial 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 integersThe 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 CoefficientIn this case, the Leading Coefficient is 9 and the Trailing Constant is -11. The factor(s) are: of the Leading Coefficient : 1,3 ,9 of the Trailing Constant : 1 ,11 Let us test ....

P	Q	P/Q	F(P/Q)	Divisor
-1	1	-1.00	-28.00
-1	3	-0.33	-11.60
-1	9	-0.11	-10.98
-11	1	-11.00	-1426348.00
-11	3	-3.67	-5901.98
-11	9	-1.22	-47.62
1	1	1.00	-4.00
1	3	0.33	-11.90
1	9	0.11	-11.19
11	1	11.00	1483196.00
11	3	3.67	6414.77
11	9	1.22	13.63

Polynomial Roots Calculator found no rational roots

Final result :

9x5 + 2x4 + 4x3 - 7x2 - x - 11
