Solution steps

(- i 2) (i 2)

Apply rule:

(- a) = - a

(- i 2) = - i 2

= - i 2 i 2

Apply radical rule:

a a = a, a \geq 0

22 = 2

= - i 2 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= - i^{2} \cdot 2

= - 2 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= - 2 (- 1)

Multiply the numbers:

- 2 (- 1) = 2

= 2

\frac{i}{- 2 - 2 i}

- 5 (- 6 k - 6) - (- 9 k - 10)

12 x^{2} (x - 1) - 4 x (x - 1) - 5 (x - 1)

36 x^{2} + 36 y^{2}

- 8 \frac{7}{10}
