Question

What is the value of the expression below when z = 6

Answer 1

94

Explanation:

3x^2 - 4x + 10 =

• replace x with 6

3 × 6² - 4 × 6 + 10 = (remember PEMDAS)

3 × 36 - 24 + 10 =

108 - 14 =

94

Answer 2

3z² - 4z + 10 = 94

Explanation:

Now we have to,

→ Evaluate the given expression.

The expression is,

→ 3z² - 4z + 10

We have to use,

→ z = 6

Let's evaluate the expression,

→ 3z² - 4z + 10

→ 3(6)² - 4(6) + 10

→ 3(36) - 4(6) + 10

→ 108 - 24 + 10

→ 84 + 10

→ 94 => {solution}

Therefore, the answer is 94.
