step 1 : 6 Simplify —— x2 Equation at the end of step 1 : 10 6 x2)+3x)-————)-2x)-15)——)+6x)+9) (x2)x^2)x2 Step 2 :Rewriting the whole as an Equivalent Fraction :

2.1 Subtracting a fraction from a whole

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

x2 + x (x2 + x) • x2 x2 + x = —————— = ————————————— 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

Step 3 :Pulling out like terms :

3.1 Pull out like factors :

x2 + x = x • (x + 1)

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:

x • (x+1) • x2 - (6) x4 + x3 - 6 ———————————————————— = ——————————— x2 x2 Equation at the end of step 3 : 10 (x4+x3-6) x2)+3x)-————)-2x)-15)—————————+6x)+9) (x2)(( x2 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 :

6x 6x • x2 6x = —— = ——————— 1 x2

its c or d take a lucky guess my dude

Answer from: Quest

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove.

an inaccurate proof leads to errors, or stating results that are not accurate. which wil mess the probelm up you dont want this
