Solution steps

(- 3) (4 i) (7 i)

Apply rule:

(- a) = - a

(- 3) = - 3

= - 3 \cdot 4 i 7 i

Multiply the numbers:

- 3 \cdot 4 \cdot 7 = - 84

= - 84 ii

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= - 84 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= - 84 (- 1)

Multiply the numbers:

- 84 (- 1) = 84

= 84

4 a^{2} c^{2} - (c^{2} - b^{2} + a^{2})^{2}

3 + \frac{1}{8}

5 i x^{2} + 11 x - 2 i

- 4 < 2 x - 2 \leq 6
