Trying to factor by pulling out :

2.2 Factoring: x4 - 3x2 + 4x - 3 Thoughtfully split the expression at hand into groups, each group having two terms:Group 1: 4x - 3Group 2: x4 - 3x2Pull out from each group separately :Group 1: (4x - 3) • (1)Group 2: (x2 - 3) • (x2)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 :

2.3 Find roots (zeroes) of : F(x) = x4 - 3x2 + 4x - 3Polynomial Roots Calculator is a set of methods aimed at finding values ofxfor 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 numberP/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 1 and the Trailing Constant is -3. The factor(s) are: of the Leading Coefficient : 1of the Trailing Constant : 1 ,3 Let us test ....
