Q. Divide. Write your answer in simplest form. 123u3+320u2
Write as Fraction: Write the division problem as a fraction.The division of a fraction by a number can be written as the multiplication of the fraction by the reciprocal of the number. So, we have:12u3+20u23÷3 can be rewritten as 12u3+20u23∗31.
Multiply Fractions: Simplify the expression by multiplying the fractions.Now, multiply the numerators and the denominators:12u3+20u23×31=(12u3+20u2)×33×1.
Simplify Multiplication: Simplify the multiplication.Since 3×1=3 and (12u3+20u2)×3=36u3+60u2, the expression simplifies to:36u3+60u23.
Factor Out GCF: Factor out the greatest common factor (GCF) from the denominator.The GCF of 36u3 and 60u2 is 12u2. Factoring out 12u2 from the denominator gives us:36u3+60u2=12u2(3u+5).
Rewrite with Factored Denominator: Rewrite the expression with the factored denominator.The expression now becomes:12u2(3u+5)3.
Cancel Common Factors: Simplify the fraction by canceling out common factors.We can cancel out a 3 from the numerator and the 12u2 in the denominator:12u2(3u+5)3=4u2(3u+5)1.
