simplify

(- 7 + i)^{2}

Solution

48 - 14 i

Solution steps

(- 7 + i)^{2}

Apply Perfect Square Formula:

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

(- 7 + i)^{2} = (- 7)^{2} + 2 (- 7) i + i^{2}

= (- 7)^{2} + 2 (- 7) i + i^{2}

Simplify

(- 7)^{2} + 2 (- 7) i + i^{2} : - 14 i + 48

= - 14 i + 48

Rewrite in standard complex form:

48 - 14 i

= 48 - 14 i
