Midterm Three Review

Chapter 7: Rational Expressions (Exam Type Questions)

In the problems below, perform the indicated operations and simplify.

  1. \dfrac{6a-6b}{a^3+b^3}\div \dfrac{a^2-b^2}{a^2-ab+b^2}
  2. \dfrac{x}{x^2-25} - \dfrac{2}{x^2-6x+5}
  3. \dfrac{1-\dfrac{6}{x}}{\dfrac{4}{x}-\dfrac{24}{x^2}}

Solve for x.

  1. \dfrac{4}{x+4}-\dfrac{5}{x-2}=5

Chapter 8: Radicals (Exam Type Questions)

Questions 5–6 are for review only and will not show up on exams.

  1. \sqrt[3]{-64}=-4 \text{ (true or false)}
  2. \sqrt[6]{-64}=-2\text{ (true or false)}

Questions similar to 7–13 will show up on exams.

For questions 7–10, simplify each expression.

  1. 4\sqrt{36}+3\sqrt{72}+\sqrt{16}
  2. \dfrac{\sqrt{300a^5b^2}}{3ab^2}
  3. \dfrac{12}{3-\sqrt{6}}
  4. \left(\dfrac{a^0b^3}{c^6d^{-12}}\right)^{\frac{1}{3}}

For questions 11–13, solve for x.

  1. \sqrt{5x-6}=x
  2. \sqrt{2x+9}+3=x
  3. \sqrt{x-3}=\sqrt{2x-5}

Chapter 9: Quadratics (Exam Type Questions)

Use the quadratic discriminant to determine the nature of the roots of each equation.

  1. \phantom{1}
    1. 2x^2 + 4x + 3 = 0
    2. 3x^2-2x-8=0

For the questions below, find the solution set by any convenient method.

  1. \phantom{1}
    1. 3x^2 = 27
    2. 2x^2=16x
  2. \phantom{1}
    1. x^2-x-12=0
    2. x^2+9x=-8
  3. \dfrac{x-3}{2}+\dfrac{6}{x+3}=1
  4. \dfrac{x-2}{x}=\dfrac{x}{x+4}

Chapter 7–9 Word Problems (Exam Type Questions)

  1. The length of a rectangle is 3 cm longer than twice the width. If the area of the rectangle is 65 cm2, find its length and width.
  2. Find three consecutive even integers such that the product of the first and the second is 68 more than the third integer.
  3. A boat cruises upriver for 8 hours and returns to its starting point in 6 hours. If the speed of the river is 4 km/h, find the speed of this boat in still water.
