Problem-Solving Strategies

The following are some general problem-solving strategies for algebra 1:

• Read the problem carefully and make sure you understand what is being asked.
• Identify the key concepts in the problem.
• Draw a diagram or create a table to help you visualize the problem.
• Write down the equations or formulas that you need to use.
• Solve the equations or formulas.
• Check your answer to make sure it makes sense.

The following are some specific problem-solving strategies for different types of problems:

• Solving equations:To solve an equation, isolate the variable on one side of the equation.
• Solving inequalities:To solve an inequality, isolate the variable on one side of the inequality and then determine the values of the variable that make the inequality true.
• Solving systems of equations:To solve a system of equations, use substitution or elimination to solve one of the variables and then solve for the other variable.
• Solving polynomials:To solve a polynomial, factor the polynomial and then set each factor equal to zero.
• Solving quadratic equations:To solve a quadratic equation, use the quadratic formula.

Sample Problems and Solutions: Algebra 1 Midterm Study Guide Answer Key

The following are some sample midterm exam problems with solutions:

1. Problem:Solve the equation 2x + 5 =

   11. Solution

   • Subtract 5 from both sides of the equation: 2x = 6
   • Divide both sides of the equation by 2: x = 3
2. Problem:Solve the inequality x3 >

   5. Solution

   • Add 3 to both sides of the inequality: x > 8
3. Problem:Solve the system of equations:
   • y = 2x + 1
   • x + y = 7

   Solution:

   • Substitute the first equation into the second equation: x + (2x + 1) = 7
   • Simplify: 3x + 1 = 7
   • Subtract 1 from both sides of the equation: 3x = 6
   • Divide both sides of the equation by 3: x = 2
   • Substitute x = 2 into the first equation: y = 2(2) + 1 = 5
4. Problem:Factor the polynomial x ²4x +

   4. Solution

   • (x – 2) ²
5. Problem:Solve the quadratic equation x ²5x + 6 =

   0. Solution

   • Use the quadratic formula: x = (-b ± √(b ²– 4ac)) / 2a
   • Substitute a = 1, b = -5, and c = 6 into the quadratic formula: x = (-(-5) ± √((-5) ²– 4(1)(6))) / 2(1)
   • Simplify: x = (5 ± √(25 – 24)) / 2
   • Simplify further: x = (5 ± 1) / 2
   • Therefore, x = 2 or x = 3.
