Question

Simplify the expression

- 8 - 6 i

Evaluate

(3 i - 1) (3 i - 1)

Apply the distributive property

3 i \times 3 i + 3 i (- 1) - 3 i - (- 1)

Multiply the numbers

More Steps

Evaluate

3 i \times 3 i

Multiply

3 \times 3 i^{2}

Multiply

9 i^{2}

Use i^{2} = - 1 to transform the expression

9 (- 1)

Calculate

- 9

- 9 + 3 i (- 1) - 3 i - (- 1)

Multiply the numbers

- 9 - 3 i - 3 i - (- 1)

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

- 9 - 3 i - 3 i + 1

Calculate

- 8 - 3 i - 3 i

Solution

More Steps

Evaluate

- 3 i - 3 i

Collect like terms by calculating the sum or difference of their coefficients

(- 1 - 1) \times 3 i

Calculate

- 2 \times 3 i

Multiply the numbers

- 6 i

- 8 - 6 i
