Q. Multiply. Write your answer in simplest form.\newlinen45n×3n2+11n4n4\frac{n - 4}{5n} \times \frac{3n^2 + 11n - 4}{n - 4}
  1. Rewrite Multiplication: Rewrite the multiplication of the two fractions. n45n×3n2+11n4n4\frac{n - 4}{5n} \times \frac{3n^2 + 11n - 4}{n - 4}
  2. Identify Expression: Identify the expression that will do the multiplication. Multiply the numerators together and the denominators together. (n4)×(3n2+11n4)5n×(n4)\frac{(n - 4) \times (3n^2 + 11n - 4)}{5n \times (n - 4)}
  3. Factor Quadratic: Factor the quadratic expression in the numerator if possible. 3n2+11n43n^2 + 11n - 4 does not factor nicely, so we leave it as is.
  4. Cancel Common Factors: Cancel out the common factors in the numerator and the denominator.\newlineThe (n4)(n - 4) terms cancel each other out.\newline(3n2+11n4)/5n(3n^2 + 11n - 4) / 5n
  5. Check Simplification: Check for any further simplification.\newlineThere are no common factors between the numerator and the denominator, so this is the simplest form.
