expand (-7i^{11}-4i^3)^2

expand

(- 7 i^{11} - 4 i^{3})^{2}

- 121

Solution steps

(- 7 i^{11} - 4 i^{3})^{2}

Apply Perfect Square Formula:

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

(- 7 i^{11} - 4 i^{3})^{2} = (- 7 i^{11})^{2} - 2 (- 7 i^{11}) \cdot 4 i^{3} + (4 i^{3})^{2}

= (- 7 i^{11})^{2} - 2 (- 7 i^{11}) \cdot 4 i^{3} + (4 i^{3})^{2}

Simplify

(- 7 i^{11})^{2} - 2 (- 7 i^{11}) \cdot 4 i^{3} + (4 i^{3})^{2} : - 121

= - 121

(x + 4)^{2} + (\frac{x ^{2}}{2} - 1)^{2}

\frac{( x ^{2} + 6 x + 9 )}{( x ^{2} - 9 )}

x (ln (u) - 2) u z

2 (j ln (t) + j - \frac{k}{t})

8 1^{u (7 p + 7 q)}
