simplify (1+10i)^2

Solution

simplify

(1 + 10 i)^{2}

Solution

- 99 + 20 i

Solution steps

(1 + 10 i)^{2}

Apply Perfect Square Formula:

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

(1 + 10 i)^{2} = 1^{2} + 2 \cdot 1 \cdot 10 i + (10 i)^{2}

= 1^{2} + 2 \cdot 1 \cdot 10 i + (10 i)^{2}

Simplify

1^{2} + 2 \cdot 1 \cdot 10 i + (10 i)^{2} : 20 i - 99

= 20 i - 99

Rewrite in standard complex form:

- 99 + 20 i

= - 99 + 20 i
