expand (x-2)(\times+2)

expand

(x - 2) (\cdot + 2)

2 x - 4

Solution steps

(x - 2) (2)

= (2) (x - 2)

Apply the distributive law:

a (b - c) = ab - a c

a = (2), b = x, c = 2

= (2) x - (2) \cdot 2

Simplify

(2) x - (2) \cdot 2 : 2 x - 4

= 2 x - 4

a^{2} + (x + Δ x)^{2} - x^{2} + a^{2}

\frac{d}{d x} ((f (x, z, y)) (z x^{2} - x y^{2} - y z^{2}))

\frac{x}{( x - 4 ) ( x - 2 )}

(\frac{16 x - 2}{4 x ^{2} + 20}) (- 4)

(1 - \frac{1}{2})^{21}
