Factor Quadratic Expression: Factor the quadratic expression in the denominator.The quadratic expression r2−7r+10 can be factored into (r−5)(r−2).r2−7r+10=(r−5)(r−2)
Write with Factored Denominator: Write the given expression with the factored denominator.(1)/(r−2)+(1)/((r−5)(r−2))=(6)/(r−2)
Find Common Denominator: Find a common denominator for the two fractions on the left side of the equation.The common denominator is (r−5)(r−2).
Rewrite with Common Denominator: Rewrite each fraction with the common denominator.(1)/(r−2)×((r−5)/(r−5))+(1)/((r−5)(r−2))=(6)/(r−2)This becomes:((r−5)+1)/((r−5)(r−2))=(6)/(r−2)
Combine Numerators: Combine the numerators of the fractions on the left side.(r−5)(r−2)(r−5)+1=(r−5)(r−2)r−5+1This simplifies to:(r−5)(r−2)r−4=r−26
Equate Numerators: Since the denominators on both sides of the equation are the same, we can equate the numerators.(r−4)=6
Solve for r: Solve for r.r−4=6r=6+4r=10
