expand (x\mid 4)(x-4)

expand

(x ∣ 4) (x - 4)

4 ∣ x^{2} - 16 ∣ x

Solution steps

(x ∣ 4) (x - 4)

= (4 ∣ x) (x - 4)

Apply the distributive law:

a (b - c) = ab - a c

a = (x ∣ 4), b = x, c = 4

= (x ∣ 4) x - (x ∣ 4) \cdot 4

= x (4 ∣ x) - 4 (4 ∣ x)

Simplify

x (4 ∣ x) - 4 (4 ∣ x) : 4 ∣ x^{2} - 16 ∣ x

= 4 ∣ x^{2} - 16 ∣ x

e^{i (wt - k x)}

- \frac{3 ( 1 - 5 ^{9375} )}{4}

e^{x} (tan (x) - x)

(d a + b c) \cdot (d a - b c)

y (x + 2) e x
