just use m a t h w a y no spaces tho
Step-by-step explanation:
Answer:
D is true, E is true, F is true
Step-by-step explanation:
Hello,
n is an odd number it means that n = 2a+1 where a is integer
A

this is <u>not</u> an odd number
B

this is <u>not</u> an odd number
C

this is <u>not</u> an odd number
D

so this is an odd number
E

so this is an odd number
F

this is an odd number
hope this helps
Answer:
- A. P(x) = x⁵ + 3x⁴ - 13x³ - 39x² + 40x + 120
Step-by-step explanation:
<u>With the given zero's, the polynomial is:</u>
- P(x) = (x - 2√2)(x - √5)(x + 3)
<u>Open parenthesis in steps:</u>
1. (x - 2√2)(x - √5) = x² - (2√2 + √5)x + 2√10 = x² - 2x√2 - x√5 + 2√10
2. (x² - 2x√2 - x√5 + 2√10)(x + 3) =
x³ - 2√2x² - √5x² + 2√10x + 3x² - 6√2x - 3√5x + 6√10 =
x³ + 3x² - 2x²√2 - x²√5 - 6x√2 - 3x√5 + 2x√10 + 6√10
This is not matching any options so we add two more zero's: -2√2 and -√5
<u>New polynomial looks like:</u>
- P(x) = (x - 2√2) (x + 2√2)( x - √5)(x - √5)(x + 3)
<u>Open parenthesis in steps:</u>
- 1. (x - 2√2) (x + 2√2) = x² - 8
- 2. (x - √5) (x + √5) = x² - 5
- 3. (x² - 8)(x² - 5) = x⁴ - 8x² - 5x² + 40 = x⁴ - 13x² + 40
- 4. (x⁴ - 13x² + 40)(x + 3) = x⁵ + 3x⁴ - 13x³ - 39x² + 40x + 120
- P(x) = x⁵ + 3x⁴ - 13x³ - 39x² + 40x + 120
Can see it can you make it bigger
Can someone help me on my recent question 5
