(xii) x6-8by x2-2 please divide as soon as possible |
|
Answer» Answer: Hope this helps you Please mark the brainlist My humble request Step-by-step explanation: Changes made to your input should not affect the SOLUTION: (1): "X2" was replaced by "x^2". 1 more similar replacement(s). STEP 1 : 8 Simplify —— x2 Equation at the end of step 1 : 8 ((x6) - ——) - 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 : x6 x6 • x2 x6 = —— = ——————— 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 : 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: x6 • x2 - (8) x8 - 8 ————————————— = —————— x2 x2 Equation at the end of step 2 : (x8 - 8) ———————— - 2 x2 STEP 3 : Rewriting the whole as an Equivalent Fraction 3.1 Subtracting a whole from a fraction Rewrite the whole as a fraction using x2 as the denominator : 2 2 • x2 2 = — = —————— 1 x2 Trying to factor as a Difference of Squares: 3.2 Factoring: x8 - 8 Theory : A difference of two perfect squares, A2 - B2 can be FACTORED into (A+B) • (A-B) Proof : (A+B) • (A-B) = A2 - AB + BA - B2 = A2 - AB + AB - B2 = A2 - B2 Note : AB = BA is the commutative property of multiplication. Note : - AB + AB equals zero and is therefore eliminated from the expression. Check : 8 is not a square !! |
