-step explanation:Step 1 : 42 SIMPLIFY —— p Equation at the end of step 1 : 42 (((p2) - p) - ——) + 6 p Step 2 :Rewriting the WHOLE as an Equivalent Fraction : 2.1 Subtracting a fraction from a wholeRewrite the whole as a fraction using p as the denominator : p2 - p (p2 - p) • p p2 - p = —————— = ———————————— 1 p Equivalent fraction : The fraction thus generated looks different but has the same value as the wholeCommon denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominatorStep 3 :PULLING out like terms : 3.1 Pull out like factors : p2 - p = p • (p - 1) Adding fractions that have a common denominator : 3.2 Adding up the two equivalent fractionsAdd the two equivalent fractions which now have a common denominatorCombine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible: p • (p-1) • p - (42) P3 - p2 - 42 ———————————————————— = ———————————— p p Equation at the end of step 3 : (p3 - p2 - 42) —————————————— + 6 p Step 4 :Rewriting the whole as an Equivalent Fraction : 4.1 Adding a whole to a fractionRewrite the whole as a fraction using p as the denominator : 6 6 • p 6 = — = ————— 1 p
