Answer 2

Calculation of Y

To calculate the value of Y in the equation Y = 3x^2 - 5x + 6, we need to substitute the given values of x into the equation.

1. When x = 5: - Y = 3(5)^2 - 5(5) + 6 - Y = 3(25) - 25 + 6 - Y = 75 - 25 + 6 - Y = 56

2. When x = -2: - Y = 3(-2)^2 - 5(-2) + 6 - Y = 3(4) + 10 + 6 - Y = 12 + 10 + 6 - Y = 28

Therefore, when x = 5, Y = 56, and when x = -2, Y = 28.
