Solution steps

Subtract the numbers:

10 - 1 = 9

= \frac{10 !}{9 ! \cdot 1 !}

Cancel the factorials:

\frac{n !}{( n - m ) !} = n \cdot (n - 1) \dots (n - m + 1), n > m

\frac{10 !}{9 !} = 10

\frac{10}{1 !} = 10

= 10

x^{2} - 2 x y + y^{2}

2 X^{2} + 4 X - 5 = 0

(x + 5) (x - 2) (x - 1) (x + 1) < 0

(1 8^{2})^{\frac{1}{3}}

6 x + x (x - 13) = 18
