Answer 2

Step-by-step explanation:

Factoring: 2x3-x2-5x-2

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: -5x-2

Group 2: 2x3-x2

Pull out from each group separately :

Group 1: (5x+2) • (-1)

Group 2: (2x-1) • (x2)

BY THE ROOT METHOD-:

Find roots (zeroes) of : F(x) = 2x3-x2-5x-2

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 Coeffic

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 CoefficientIn this case, the Leading Coefficient is 2 and the Trailing Constant is -2. The factor(s) are:of the Leading Coefficient : 1,2

of the Trailing Constant : 1 ,2
