Answer:
and the question is...
Step-by-step explanation:
1) given x^4 + 95x^2 - 500
2) split in two factors with common factor term x^2: (x^2 + )(x^2 - )
3) find two numbers that add up 95 and their product is - 500:
=> 100*(-5) = - 500 and 100 - 5 = 95
=> (x^2 + 100)(x^2 - 5)
4) factor x^2 - 5 = (x + √5) (x - √5)
5) write the prime factors: (x^2 + 100) (x + √5) (x -√5)
6) find the solutions:
x^2 + 100 = 0 => not possible
x + √5 = 0 => x = - √5
x - √5 = 0 => x = √5
Answer: x = √5 and x = - √5
Answer:
8.4*10^-3
Step-by-step explanation:
Move the decimal point 3 places in order to get a number in the one's place.
Answer:
short course meter pool and its longer by 7.021 feet or 7.02 ft
Step-by-step explanation:
if you do 25 yards times 3 you get 75ft and if you covert 25 meters into ft you get 82.021 so sutract 82.02-75=7.02. Hope this helps ;-)
