Solution steps

(7 - x)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(7 - x)^{2} = 7^{2} - 2 \cdot 7 x + (x)^{2}

= 7^{2} - 2 \cdot 7 x + (x)^{2}

7^{2} = 49

- 2 \cdot 7 x = - 14 x

(x)^{2} = x

= 49 - 14 x + x

\frac{16 ( 3 - 5 )}{5}

(a - 2) l e f t (a + 12)

(1 - \frac{1}{x})^{20}

(1 + x)^{3}

(5 - x^{3}) (2 - \frac{3}{x + 1})
