Q. Divide. Write your answer in simplest form. \newline25d+207d2÷3d13d+2\frac{25d + 20}{7d^2} \div \frac{3d - 1}{3d + 2}
  1. Rewrite as multiplication: Rewrite the division problem as a multiplication problem by taking the reciprocal of the second fraction.\newlineThe original problem is: (25d+20)/(7d2)÷(3d1)/(3d+2)(25d + 20)/(7d^2) \div (3d - 1)/(3d + 2)\newlineWe can rewrite this as: (25d+20)/(7d2)×(3d+2)/(3d1)(25d + 20)/(7d^2) \times (3d + 2)/(3d - 1)
  2. Factor out common factor: Factor out the common factor in the numerator of the first fraction if possible.\newlineIn the numerator of the first fraction, 25d+2025d + 20, we can factor out a 55: 5(5d+4)5(5d + 4)\newlineThe expression now looks like: (5(5d+4))/(7d2)×(3d+2)/(3d1)(5(5d + 4))/(7d^2) \times (3d + 2)/(3d - 1)
  3. Multiply numerators and denominators: Multiply the numerators and the denominators of the two fractions.\newlineThe numerators are (5(5d+4))(5(5d + 4)) and (3d+2)(3d + 2), and the denominators are (7d2)(7d^2) and (3d1)(3d - 1).\newlineMultiplying the numerators: (5(5d+4))(3d+2)(5(5d + 4))(3d + 2)\newlineMultiplying the denominators: (7d2)(3d1)(7d^2)(3d - 1)\newlineThe expression now looks like: (5(5d+4))(3d+2)(7d2)(3d1)\frac{(5(5d + 4))(3d + 2)}{(7d^2)(3d - 1)}
  4. Simplify by expanding and canceling: Simplify the expression by expanding the numerators and denominators if possible and then canceling out common factors.\newlineExpanding the numerator: 5(5d+4)(3d+2)=5(15d2+10d+12d+8)=5(15d2+22d+8)5(5d + 4)(3d + 2) = 5(15d^2 + 10d + 12d + 8) = 5(15d^2 + 22d + 8)\newlineExpanding the denominator: (7d2)(3d1)=21d37d2(7d^2)(3d - 1) = 21d^3 - 7d^2\newlineThe expression now looks like: 5(15d2+22d+8)21d37d2\frac{5(15d^2 + 22d + 8)}{21d^3 - 7d^2}
  5. Check for common factors: Check for any common factors that can be canceled out from the numerator and the denominator.\newlineThere are no common factors between the numerator 5(15d2+22d+8)5(15d^2 + 22d + 8) and the denominator 21d37d221d^3 - 7d^2.\newlineTherefore, the expression is already in its simplest form.
  6. Write final answer: Write the final answer.\newlineThe simplest form of the expression is: (5(15d2+22d+8)21d37d2)(\frac{5(15d^2 + 22d + 8)}{21d^3 - 7d^2})
