30x3 - 5x244
Simplify ————————————
5x2 - 5x6
Step 6 :
Pulling out like terms :
6.1 Pull out like factors :
30x3 - 5x244 = 5x3 • (6 - x241)
Step 7 :
Pulling out like terms :
7.1 Pull out like factors :
5x2 - 5x6 = -5x2 • (x4 - 1)
Trying to factor as a Difference of Squares :
7.2 Factoring: x4 - 1
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 1 is the square of 1
Check : x4 is the square of x2
Factorization is : (x2 + 1) • (x2 - 1)
Polynomial Roots Calculator :
7.3 Find roots (zeroes) of : F(x) = x2 + 1
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 1.
The factor(s) are:
of the Leading Coefficient : 1
of the Trailing Constant : 1
Let us test ....

Trying to factor as a Difference of Squares :
7.4 Factoring: x2 - 1
Check : 1 is the square of 1
Check : x2 is the square of x1
Factorization is : (x + 1) • (x - 1)
Dividing exponential expressions :

Attempted Long division of
6 - x241
By :
-x2 - 1
Was aborted due to the followinf reason :
Power of dividend too high for Tiger to process
Step 8 :
Pulling out like terms :
8.1 Pull out like factors :
-x2 - 1 = -1 • (x2 + 1)
Polynomial Roots Calculator :
8.2 Find roots (zeroes) of : F(x) = x2 + 1
See theory in step 7.3
In this case, the Leading Coefficient is 1 and the Trailing Constant is 1.
The factor(s) are:
of the Leading Coefficient : 1
of the Trailing Constant : 1
