expand (2,3i)(2,-3i)

expand

(2, 3 i) (2, - 3 i)

2 (2 \cdot 3 i,), - 3 i (2 \cdot 3 i,)

Solution steps

(2, 3 i) (2, - 3 i)

= (2 \cdot 3 i,) (2, - 3 i)

Apply the distributive law:

a (b - c) = ab - a c

a = (2, 3 i), b = 2,, c = 3 i

= (2, 3 i) \cdot 2, - (2, 3 i) \cdot 3 i

= 2 (2 \cdot 3 i,), - 3 i (2 \cdot 3 i,)

3 (e^{t} - 1)^{2}

(e^{j t} - e^{- j t})^{5}

(y^{3} + k x y^{4} - 10 x) d x + (3 x y^{2} + 29 x^{2} y^{3})

\frac{d}{d x} ((2 - x^{2}) cos (x^{2})) + 2 x sin (x^{2})

(1 + tan (x))^{3}
