Q. Simplify the expression below and write your answer in simplest form: x(x+10)2x2+10x⋅x2+19x+90(x+10)2
Write Expression: Write down the expression to be simplified.(x2+10x)/(x(x+10)2)×((x+10)2)/(x2+19x+90)
Factor Denominator: Factor the denominator of the second fraction if possible.x2+19x+90 can be factored into (x+10)(x+9).So, the expression becomes:x(x+10)2x2+10x×(x+10)(x+9)(x+10)2
Cancel Common Factors: Cancel out common factors from the numerator and the denominator.The (x+10)2 in the numerator cancels with one (x+10) in the denominator and the remaining (x+10) in the numerator.The x in the denominator of the first fraction cancels with the x in the numerator of the second fraction.The expression simplifies to:(x2+10x)/(x(x+10))×1/(x+9)=(x(x+10))/(x(x+10))×1/(x+9)=1×1/(x+9)=1/(x+9)
Final Simplified Expression: Write down the final simplified expression.The final simplified expression is (x+9)1.
