5. Mastering Algebra 2: Practical Examples

To truly master Algebra 2, it’s essential to work through a variety of practice problems that illustrate the application of key concepts and formulas. Here are a few examples to get you started:

5.1. Solving Quadratic Equations

Problem: Solve the quadratic equation 2x² + 5x – 3 = 0 using the quadratic formula.

Solution:

1. Identify the coefficients: a = 2, b = 5, c = -3.

2. Apply the quadratic formula:

   x = (-b ± √(b² – 4ac)) / (2a)

   x = (-5 ± √(5² – 4(2)(-3))) / (2(2))

   x = (-5 ± √(25 + 24)) / 4

   x = (-5 ± √49) / 4

   x = (-5 ± 7) / 4

3. Find the two solutions:

   x₁ = (-5 + 7) / 4 = 2 / 4 = 1/2

   x₂ = (-5 – 7) / 4 = -12 / 4 = -3

   Therefore, the solutions are x = 1/2 and x = -3.

5.2. Working with Exponential Functions

Problem: A population of bacteria doubles every 3 hours. If the initial population is 100, how many bacteria will there be after 12 hours?

Solution:

1. Identify the variables:

   P = 100 (initial population)

   r = 1 (doubling means 100% growth)

   t = 12 hours

2. Determine the number of doubling periods:

   Number of periods = t / doubling time = 12 / 3 = 4

3. Apply the exponential growth formula:

   A = P(1 + r)ⁿ, where n is the number of doubling periods.

   A = 100(1 + 1)⁴

   A = 100(2)⁴

   A = 100(16)

   A = 1600

   Therefore, there will be 1600 bacteria after 12 hours.

5.3. Graphing Trigonometric Functions

Problem: Graph the function y = 2sin(x) for 0 ≤ x ≤ 2π.

Solution:

1. Identify the amplitude: The amplitude is 2, which means the maximum value of the function is 2 and the minimum value is -2.

2. Identify the period: The period of the sine function is 2π, so the function completes one full cycle in the interval [0, 2π].

3. Find key points:

   x = 0: y = 2sin(0) = 0

   x = π/2: y = 2sin(π/2) = 2

   x = π: y = 2sin(π) = 0

   x = 3π/2: y = 2sin(3π/2) = -2

   x = 2π: y = 2sin(2π) = 0

4. Plot the points and draw the graph: Plot the key points and connect them with a smooth curve to create the graph of y = 2sin(x).

5.4. Solving Logarithmic Equations

Problem: Solve the logarithmic equation log₂(3x – 1) = 3.

Solution:

1. Convert to exponential form:

   log₂(3x – 1) = 3 is equivalent to 2³ = 3x – 1

2. Simplify:

   8 = 3x – 1

3. Solve for x:

   9 = 3x

   x = 3

   Therefore, the solution is x = 3.

5.5. Working with Sequences and Series

Problem: Find the sum of the first 10 terms of the arithmetic sequence 2, 5, 8, 11, …

Solution:

1. Identify the variables:

   a₁ = 2 (first term)

   d = 3 (common difference)

   n = 10 (number of terms)

2. Find the 10th term:

   aₙ = a₁ + (n – 1)d

   a₁₀ = 2 + (10 – 1)3

   a₁₀ = 2 + 27

   a₁₀ = 29

3. Apply the arithmetic series formula:

   Sₙ = n/2 (a₁ + aₙ)

   S₁₀ = 10/2 (2 + 29)

   S₁₀ = 5 (31)

   S₁₀ = 155

   Therefore, the sum of the first 10 terms is 155.
