Step-by-step explanation:

Answer 2

Answer:

STEP-1:

2

Simplify —

x

Equation at the end of step 1:

1 2

((((x2)+————)+2)-2x)-—

(x2) x

STEP 2 :

1

Simplify ——

x2

Equation at the end of step 2:

1 2

((((x2) + ——) + 2) - 2x) - —

x2 x

STEP 3 :

Rewriting the whole as an Equivalent Fraction :

3.1 Adding a fraction to a whole

Rewrite the whole as a fraction using x2 as the denominator :

x2 x2 • x2

x2 = —— = ———————

1 x2

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

x2 • x2 + 1 x4 + 1

——————————— = ——————

x2 x2

Equation at the end of step 3:

(x4 + 1) 2

((———————— + 2) - 2x) - —

x2 x

STEP 4:

Rewriting the whole as an Equivalent Fraction :

4.1 Adding a whole to a fraction

Rewrite the whole as a fraction using x2 as the denominator :

2 2 • x2

2 = — = ——————

1 x2

Polynomial Roots Calculator :

4.2 Find roots (zeroes) of : F(x) = x4 + 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
