simplify x(x+3i)(x-2i)-xi

simplify

x (x + 3 i) (x - 2 i) - x i

x ((x^{2} + 6) + x i) - x i

Solution steps

x (x + 3 i) (x - 2 i) - x i

Apply complex arithmetic rule:

(a + bi) (c + d i) = (a c - b d) + (a d + b c) i

x (x + 3 i) (x - 2 i) = x ((xx - 3 (- 2)) + (x (- 2) + 3 x) i)

= x ((xx - 3 (- 2)) + (x (- 2) + 3 x) i) - x i

Simplify

(xx - 3 (- 2)) + (x (- 2) + 3 x) i : (x^{2} + 6) + x i

= x ((x^{2} + 6) + x i) - x i

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

(cos (x) + x sin (x))^{2}

\frac{4 x ( 14 x ^{2} - x ^{3} )}{147}

\frac{( x - 1 ) ( x + 5 )}{x - 5}

\frac{( x - y ) ^{3}}{x + y}
