(x - 5i√2)(x +5i√2)
given the roots of a polynomial p(x), say x = a and x = b
then the factors are (x - a)(x - b)
and p(x) is the product of the factors ⇒ p(x) = (x - a)(x - b)
here x² + 50 = 0 ⇒ x² = - 50 → ( set = 0 for roots)
take the square root of both sides
x = ± √-50 = ± √(25 × 2 × -1) = √25 × √2 × √-1 = ± 5i√2
The roots are x = ± 5i√2
thus the factors are ( x - ( - 5i√2)) and (x - (+5i√2))
x² + 50 = (x + 5i√2)(x - 5i√2)
Answer:
65% profit
-25% discount
Step-by-step explanation:
cost price = 40+25 = 65% higher than marked price
discount = -25%
To solve this we would do 30×365
We would do this because each day the dog 30lbs
So we have the equation y=30x
Where y= total amount of dog food
And x= number of days
In a year there are 365 days typically, so we do 30×365
30×365=10,950
In one year 10,950 lbs of dog food are used

Answer:
B
Step-by-step explanation:
Given
6p³ - 12p² + 9p ← factor out 3p from each term
= 3p(2p² - 4p + 3) → B
