Step by step solution :Step 1 :Equation at the end of step 1 :((((x4)+(x3))-23x2)-3x)+60 = 0Step 2 :Polynomial Roots Calculator : 2.1 Find roots (zeroes) of : F(x) = x4+x3-23x2-3x+60 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 The factor(s) are: of the Leading Coefficient : 1 1 ,2 ,3 ,4 ,5 ,6 ,10 ,12 ,15 ,20 , etc Let us test ....

Quotient : x2-3 Remainder: 0 Trying to factor as a Difference of Squares :2.5 Factoring: x2-3 Theory : A difference of two perfect squares, A2 - B2 can be factored into Proof : (A+B) • (A-B) = Note : - AB + AB equals zero and is therefore eliminated from the expression. Check : 3 is not a square !!Ruling : Binomial can not be factored as the difference of two perfect squares. Equation at the end of step 2 :(x2 - 3) • (x + 5) • (x - 4) = 0Step 3 :Theory - Roots of a product :3.1 A product of several terms equals zero.When a product of two or more terms equals zero, then at least one of the terms must be zero.We shall now solve each term = 0 separatelyIn other words, we are going to solve as many equations as there are terms in the productAny solution of term = 0 solves product = 0 as well. Solving a Single Variable Equation : 3.2 Solve : x2-3 = 0Add 3 to both sides of the equation : Solving a Single Variable Equation : 3.3 Solve : x+5 = 0Subtract 5 from both sides of the equation : Solving a Single Variable Equation : 3.4 Solve : x-4 = 0Add 4 to both sides of the equation : Four solutions were found :
