Question

X(x+4)-(x-3)(x-5)= При х= 1/6

Answer 1

$x(x + 4) - (x - 3)( x - 5) = \\ = x {}^{2} + 4x - x {}^{2} + 5x + 3x - 15 = \\ = 4x + 5x + 3x - 15 = \\ = 12x - 15 \\ x = \frac{1}{6} \\ 12 \times \frac{1}{6} - 15 = 2 - 15 = - 13$

Answer 2

To find the value of the expression X(x+4)-(x-3)(x-5) when x = 1/6, we simply need to substitute the value of x into the expression and perform the calculations.

Let's proceed step by step:

1. Replace x with 1/6 in the expression: X(1/6 + 4) - (1/6 - 3)(1/6 - 5)

2. Simplify the expressions inside the parentheses: X(25/6) - (-17/6)(-29/6)

3. Perform the multiplication inside the parentheses: X(25/6) - (493/36)

4. To get the final result, subtract (493/36) from X(25/6):

Final Result = X(25/6) - (493/36)

Unfortunately, without knowing the value of X, we cannot compute the exact numerical result. If you have the value of X, please provide it, and I can help you calculate the final answer.
