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: See explanation
Step-by-step explanation:
Let the number of hours used for softball practice be x.
Since soccer practice is 1.5 more hours more than 3 times as long as the softball practice. This will be:
= (3 × x) + 1.5 = 3x + 1.5
Therefore, we add both and equate to 15.
x + 3x + 1.5 = 15
4x + 1.5 = 15
4x = 15 - 1.5
4x = 13.5
x = 13.5/4
x = 3.375
Softball is practiced for 3.375 hours
