Solution steps

(- 3 + - 16)^{2}

Apply Perfect Square Formula:

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

(- 3 + - 16)^{2} = (- 3)^{2} + 2 (- 3) - 16 + (- 16)^{2}

= (- 3)^{2} + 2 (- 3) - 16 + (- 16)^{2}

(- 3)^{2} + 2 (- 3) - 16 + (- 16)^{2} = - 24 i - 7

= - 24 i - 7

Rewrite in standard complex form:

- 7 - 24 i

= - 7 - 24 i
