Factor Quadratic Expressions: Factor the quadratic expressions where possible.The quadratic expression p2+2p−15 can be factored into (p+5)(p−3) because (p+5)(p−3)=p2−3p+5p−15=p2+2p−15.The quadratic expression p2−25 can be factored into (p+5)(p−5) because (p+5)(p−5)=p2−5p+5p−25=p2−25.
Rewrite with Factored Forms: Rewrite the original expression with the factored forms.The expression becomes (5p2)/((p+5)(p−3))×((p+5)(p−5))/(25p).
Cancel Common Factors: Cancel out common factors.We can cancel out the common factor of (p+5) from the numerator of the first fraction and the numerator of the second fraction.We can also cancel out p from 5p2 in the numerator of the first fraction and 25p in the denominator of the second fraction.The expression now simplifies to p−35p×25p−5.
Simplify Further: Simplify the expression further.We can cancel out the common factor of 5 from 5p in the numerator and 25 in the denominator.The expression now simplifies to p−3p×5p−5.
Multiply Remaining Expressions: Multiply the remaining expressions. Multiplying the numerators together and the denominators together, we get (p×(p−5))/((p−3)×5).
Expand Numerator: Expand the numerator.Expanding the numerator, we get p2−5p.The expression now is (p2−5p)/((p−3)⋅5).
Leave Denominator Factored: Leave the denominator in factored form.The final simplified expression is (p2−5p)/(5(p−3)).
