expand x^2+i^3x+i^2

expand

x^{2} + i^{3} x + i^{2}

(x^{2} - 1) - i x

Solution steps

x^{2} + i^{3} x + i^{2}

i^{3} = - i

= x^{2} - i x + i^{2}

Apply imaginary number rule:

i^{2} = - 1

= x^{2} - i x - 1

Rewrite

x^{2} - i x - 1

in standard complex form:

(x^{2} - 1) - x i

= (x^{2} - 1) - x i

\frac{10}{( x + 1 ) ^{3}}

l [(1 + e^{2 t})^{2}]

d x (cos (x) + sin (x))

\frac{2 ( 1 - ln ( x ) )}{x ^{2}}

\frac{4 π ( 20 10 - 10 5 )}{3}
