- 2 i \cdot (- 5) i

- 10

Solution steps

- 2 i (- 5) i

Multiply the numbers:

2 (- 5) = - 10

= - (- 10) ii

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= - (- 10) i^{2}

Remove parentheses:

- (- 10) i^{2} = 10 i^{2}

= 10 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 10 (- 1)

Multiply the numbers:

10 (- 1) = - 10

= - 10

(4 x + 2) (6 x^{2} - x + 2)

x^{2} - 12 x + 27

x^{4} + 2 x^{3} - 4 x^{2} - 8 x
