Question

What is the value of 3x^2 + 5x - 2 when x = 4?

Answer 1

66

Explanation:

Plug 4 in for x:

(3 · 4²) + (5 · 4) - 2

(3 · 16) + 20 - 2

48 + 20 - 2 = 66

Answer 2

The value of 3x^2 + 5x - 2 when x = 4 is 66.

Explanation:

To find the value of 3x^2 + 5x - 2 when x = 4, substitute x = 4 into the expression:

3(4)^2 + 5(4) - 2

This simplifies to:

3(16) + 20 - 2

48 + 20 - 2

68 - 2

The value of 3x^2 + 5x - 2 when x = 4 is 66.
