Q. Divide. Write your answer in simplest form.\newline8s9s215s+4÷35s+2\frac{8s}{9s^2 - 15s + 4} \div \frac{3}{5s + 2}
  1. Rewrite division as multiplication: Write the division of the two fractions as a multiplication by the reciprocal of the second fraction.\newlineWe have: (8s9s215s+4)÷(35s+2)(\frac{8s}{9s^2 - 15s + 4}) \div (\frac{3}{5s + 2})\newlineThis can be rewritten as: (8s9s215s+4)×(5s+23)(\frac{8s}{9s^2 - 15s + 4}) \times (\frac{5s + 2}{3})
  2. Factor quadratic expression: Factor the quadratic expression in the denominator of the first fraction if possible.\newlineThe quadratic expression is 9s215s+49s^2 - 15s + 4. We need to check if it can be factored.\newlineFactoring attempt: (3s4)(3s1)=9s23s12s+4=9s215s+4(3s - 4)(3s - 1) = 9s^2 - 3s - 12s + 4 = 9s^2 - 15s + 4\newlineSo, the factored form is correct.\newlineThe first fraction becomes: (8s(3s4)(3s1))(\frac{8s}{(3s - 4)(3s - 1)})
  3. Multiply numerators and denominators: Multiply the numerators and the denominators of the two fractions.\newlineWe have: (8s(3s4)(3s1))×5s+23(\frac{8s}{(3s - 4)(3s - 1)}) \times \frac{5s + 2}{3}\newlineMultiplying the numerators: 8s×(5s+2)=40s2+16s8s \times (5s + 2) = 40s^2 + 16s\newlineMultiplying the denominators: (3s4)(3s1)×3=3(3s4)(3s1)(3s - 4)(3s - 1) \times 3 = 3(3s - 4)(3s - 1)\newlineThe expression becomes: 40s2+16s3(3s4)(3s1)\frac{40s^2 + 16s}{3(3s - 4)(3s - 1)}
  4. Simplify expression: Simplify the expression if possible.\newlineWe look for common factors in the numerator and the denominator.\newlineThere are no common factors between 40s2+16s40s^2 + 16s and (3s4)(3s1)(3s - 4)(3s - 1).\newlineSo, the expression is already in its simplest form.
