$(x - (4 + i)) (x - (4 - i))$

Step 1

Apply the distributive property.

$(x - 1 \cdot 4 - i) (x - (4 - i))$

Step 2

Multiply $- 1$ by $4$ .

$(x - 4 - i) (x - (4 - i))$

Step 3

Apply the distributive property.

$(x - 4 - i) (x - 1 \cdot 4 - - i)$

Step 4

Multiply $- 1$ by $4$ .

$(x - 4 - i) (x - 4 - - i)$

Step 5

Multiply $- 1$ by $- 1$ .

$(x - 4 - i) (x - 4 + 1 i)$

Step 6

Multiply $i$ by $1$ .

$(x - 4 - i) (x - 4 + i)$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
