Evaluating expressions with order of operations, ((a^2)/4b)+c When a=12, b=9 and c=4

The video tutorial guides students through solving a mathematical expression by substituting given values for variables and applying the order of operations. The instructor demonstrates step-by-step calculations, emphasizing the importance of using parentheses and verifying results. The final solution is reached through careful arithmetic, and students are encouraged to check their work.

What is the expression that the teacher is trying to evaluate?

• a^2 * 4B - C

• a^2 + 4B / C

• a^2 - 4B + C

• a^2 / 4B + C

What are the given values for a, B, and C in the problem?

• a = 11, B = 6, C = 2

• a = 15, B = 7, C = 3

• a = 12, B = 9, C = 4

• a = 10, B = 8, C = 5

What is the first step in solving the expression after substituting the values?

• Square the value of a

• Multiply the values

• Add the values

• Divide the value of B
