Answer:
f(x) = 
Step-by-step explanation:
First of all, if 2 - i is a zero, then so is 2 + i
All you need to do now is multiply (x - 1)(x - 3)(x - 2 + i)(x - 2 - i)
I will do part of that multiplication
(x - 2 + i)(x - 2 - i) = 
- 2x - xi - 2x + 4 + 2i + xi - 2i - 
= - 4x + 5
So, now (x - 1)(x - 3)( - 4x + 5) =
I will let you finish that multiplication. I did some and you can do some. OK?
Answer:
X=4, y=1
Step-by-step explanation:
Answer:
50/3
Step-by-step explanation:
For x
3x-2(2+1)=4
3x-2(3)=4
3x-6=4
3x=4+6
3x=10
x=10/3
as we have to find 5x=?
5(10/3)
50/3
When changing from radical form to fractional exponents, remember these basic forms:
The nth root of a can be written as a fractional exponent with a raised to the reciprocal of that power.
is taken, it’s raised to the 1/n power. When a power is raised to another power, you multiply the powers together, and so the m (otherwise written as m/1) and the 1/n are multiplied together.
Use fractions in the powers to indicate that the expression stands for a root or a radical.
Leave the exponent as 9/4. Don’t write it as a mixed number.
