simplify (4+6i)^2

Solution

simplify

(4 + 6 i)^{2}

Solution

- 20 + 48 i

Solution steps

(4 + 6 i)^{2}

Apply Perfect Square Formula:

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

(4 + 6 i)^{2} = 4^{2} + 2 \cdot 4 \cdot 6 i + (6 i)^{2}

= 4^{2} + 2 \cdot 4 \cdot 6 i + (6 i)^{2}

Simplify

4^{2} + 2 \cdot 4 \cdot 6 i + (6 i)^{2} : 48 i - 20

= 48 i - 20

Rewrite in standard complex form:

- 20 + 48 i

= - 20 + 48 i
