(x3-3x2+3x-2)/(x2-x+1)

This deals with finding the root (zeroes) of polynomials.

You are watching: What is the quotient (x3 – 3x2 + 3x – 2) ÷ (x2 – x + 1)?

Step 2 :

x3 - 3x2 + 3x - 2 simplify ————————————————— x2 - x + 1 Checking because that a perfect cube :2.1x3 - 3x2 + 3x - 2 is no a perfect cube

Trying to variable by pulling the end :

2.2 Factoring: x3 - 3x2 + 3x - 2 Thoughtfully split the expression at your disposal into groups, each team having 2 terms:Group 1: 3x - 2Group 2: -3x2 + x3Pull the end from each group separately :Group 1: (3x - 2) • (1)Group 2: (x - 3) • (x2)Bad news no Factoring through pulling out fails : The teams have no usual factor and can not be included up to form a multiplication.

Polynomial roots Calculator :

2.3 uncover roots (zeroes) the : F(x) = x3 - 3x2 + 3x - 2Polynomial root Calculator is a collection of techniques aimed at finding values ofxfor i beg your pardon F(x)=0 Rational root Test is one of the over mentioned tools. It would only find Rational Roots that is numbers x which deserve to be expressed as the quotient of 2 integersThe Rational root Theorem says that if a polynomial zeroes because that a reasonable numberP/Q then p is a variable of the Trailing consistent and Q is a variable of the leading CoefficientIn this case, the leading Coefficient is 1 and the Trailing consistent is -2. The factor(s) are: of the leading Coefficient : 1of the Trailing constant : 1 ,2 Let united state test ....

The element Theorem states that if P/Q is root of a polynomial then this polynomial have the right to be separated by q*x-p keep in mind that q and also p originate from P/Q diminished to the lowest terms In our situation this means that x3 - 3x2 + 3x - 2can be separated with x - 2

Trying to aspect by splitting the center term

2.5Factoring x2-x+1 The first term is, x2 that coefficient is 1.The center term is, -x the coefficient is -1.The critical term, "the constant", is +1Step-1 : multiply the coefficient of the first term by the constant 1•1=1Step-2 : find two factors of 1 whose sum equates to the coefficient the the middle term, i m sorry is -1.

-1+-1=-2
1+1=2

Observation : No two such factors can be found !! Conclusion : Trinomial have the right to not it is in factored

Trying to factor by separating the middle term

2.6Factoring x2-x+1 The first term is, x2 that coefficient is 1.The middle term is, -x the coefficient is -1.The last term, "the constant", is +1Step-1 : multiply the coefficient of the an initial term by the consistent 1•1=1Step-2 : discover two factors of 1 who sum equals the coefficient the the center term, which is -1.

Observation : No two such determinants can be discovered !! Conclusion : Trinomial have the right to not it is in factored
