simplify (i-2)^2

Solution

simplify

(i - 2)^{2}

Solution

3 - 4 i

Solution steps

(i - 2)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

i^{2} - 2 i 2 + 2^{2} : - 4 i + 3

= - 4 i + 3

Rewrite in standard complex form:

3 - 4 i

= 3 - 4 i
