Answer

4[^x C_{x-1}] $, find the values of$ x$.

Here are the solutions to the mathematics questions.

9. (a) If $^x C_2 = 4[^x C_{x-1}]$ , find the values of $x$ .

Step 1: Use the combination formula $^n C_r = \frac{n!}{r!(n-r)!}$ and the property $^n C_r = ^n C_{n-r}$ . We are given $^x C_2 = 4[^x C_{x-1}]$ . Using the property, $^x C_{x-1} = ^x C_{x-(x-1)} = ^x C_1$ . So the equation becomes: $^x C_2 = 4(^x C_1)$
