<u>Answer</u>
d) 2 – i
<u>Explanation</u>
f(x) = x³ – 2x²
When x = i, we proceed as follows.
Note: i =
i² =(√-1)(√-1) = -1
i³ = (√-1)(√-1)(√-1) = -1(√-1) = -1i = -i
f(x) = x³ – 2x²
f(i) = i³ – 2i²
= -i – 2(-1)
= -i + 2
= 2 – i
Answer:
39
Step-by-step explanation:
1 Collect like terms
(−y3+4y3)+(−7+4)+(11x2+2x2)
2 Simplify 3y3−3+13x2 to:
3{y}^{3}-3+13{x}^{2}
Answer: 3y^3−3+13x^2
Simplifying the expression would be 19.76.
