expand (((2+2i))/2)^2

expand

(\frac{( 2 + 2 i )}{2})^{2}

2 i

Solution steps

(\frac{2 + 2 i}{2})^{2}

\frac{2 + 2 i}{2} = 1 + i

= (1 + i)^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

a = 1, b = i

= 1^{2} + 2 \cdot 1 i + i^{2}

Simplify

1^{2} + 2 \cdot 1 i + i^{2} : 2 i

= 2 i

\frac{3 x ^{2}}{( l - x ) ^{2}}

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

(n \cdot (n + 1)) 2

(b + 5) x^{'}

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