expand (3i,-1j)(4i,2j)

expand

(3 i, - 1 j) (4 i, 2 j)

3 i (4 \cdot 2 i, j), - 1 \cdot j (4 \cdot 2 i, j)

Solution steps

(3 i, - 1 \cdot j) (4 i, 2 j)

= (3 i, - 1 \cdot j) (4 \cdot 2 i, j)

Apply the distributive law:

a (b - c) = ab - a c

a = (4 i, 2 j), b = 3 i,, c = 1 \cdot j

= (4 i, 2 j) \cdot 3 i, - (4 i, 2 j) \cdot 1 \cdot j

= 3 i (4 \cdot 2 i, j), - 1 \cdot j (4 \cdot 2 i, j)

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

(2 x + 1) l e f t (2 x - 1)

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

(14 + x^{2} + y^{2} + z^{2})^{2}

(s + 1 + i) (s + 1 - i)
