expand (x-1)(x-2/x =1)

expand

(x - 1) (x - \frac{2}{x} = 1)

x^{2} - 2 = 1

Solution steps

(x - 1) (x - \frac{2}{x} = 1)

= (x - 1) (x - 1 = \frac{2}{x})

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = x, b = - 1, c = x, d = - \frac{2}{x} = 1

= xx + x (- \frac{2}{x} = 1) + (- 1) x + (- 1) (- \frac{2}{x} = 1)

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

xx - \frac{2}{x} x = 1 - 1 \cdot x + 1 \cdot \frac{2}{x} = 1

Expand

xx - \frac{2}{x} x : x^{2} - 2

x^{2} - 2 = 1

- \frac{27}{7 \cdot ( s + 3 ) ^{2}}

x y + x^{2} + 1 + (x^{2} + x) \cdot \frac{d y}{d x}

- lo g_{10} (8.41)

\frac{( 7 - 3 s )}{( s + 2 ) ^{4}}

e^{(2 + i) t} - e^{(2 - i) t}
