expand (s+16+9i)(s+16-9i)

expand

(s + 16 + 9 i) (s + 16 - 9 i)

s^{2} + 32 s + 337

Solution steps

(s + 16 + 9 i) (s + 16 - 9 i)

Distribute parentheses

= ss + s \cdot 16 + s (- 9 i) + 16 s + 16 \cdot 16 + 16 (- 9 i) + 9 i s + 9 i 16 + 9 i (- 9 i)

Simplify

ss + s \cdot 16 + s (- 9 i) + 16 s + 16 \cdot 16 + 16 (- 9 i) + 9 i s + 9 i 16 + 9 i (- 9 i) : s^{2} + 32 s + 337

= s^{2} + 32 s + 337

\frac{\partial}{\partial x} (2 x) + 3 y^{2} (1 + x)^{2}

(x - 9 + 1)^{2}

\frac{π ( 9 - h ^{2} ) ( h + 3 )}{3}

\frac{x ^{x^{2}}}{( x + 1 ) ^{(x + 1)^{2}}}

lo g_{10} (10) x^{2}
