x^2 - 2x + 2
x = 1 + i
(1 + i)^2 - 2(1 + i) + 2
<em><u>Distributive property.</u></em>
(1 + i)(1 + i) - 2 - 2i + 2
<em><u>Continue distributive property on left side.</u></em>
1 + i + i + i^2 - 2 - 2i + 2
<em><u>Combine like terms.</u></em>
1 + 2i + i^2 - 2 - 2i + 2
1 + i^2
<em><u>i^2 can be interpreted as -1.</u></em>
1 - 1 = 0
The expression is equal to 0.
Answer:
1)Clear parenthesis on both sides of the inequality and collect like terms.
2)Add or subtract terms so the variable is on one side and the constant is on the other side of the inequality sign.
3)Multiply and divide by whatever constants are attached to the variable.
