​

Answer 1

Answer:

((x^2+1)*(2x+1))/(2x)

hope it helps you follow

Step-by-step explanation:

STEP1:

1 Simplify — 2

Equation at the end of step1:

1 1 (x + —) • (x - —) x 2

STEP2:Rewriting the whole as an Equivalent Fraction

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  2  as the denominator :

x x • 2 x = — = ————— 1 2

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 :

 2.2       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:

x • 2 - (1) 2x - 1 ——————————— = —————— 2 2

Equation at the end of step2:

1 (2x - 1) (x + —) • ———————— x 2

STEP3:

1 Simplify — x

Equation at the end of step3:

1 (2x - 1) (x + —) • ———————— x 2

STEP4:

Rewriting the whole as an Equivalent Fraction :

 4.1   Adding a fraction to a whole

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

x x • x x = — = ————— 1 x

Adding fractions that have a common denominator :

 4.2       Adding up the two equivalent fractions

x • x + 1 x2 + 1 ————————— = —————— x x

Equation at the end of step4:

(x2 + 1) (2x - 1) ———————— • ———————— x 2
