I hope this helps
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
When you're subtracting negatives, you're adding them so... Here's a tip:
-9 - (-83)
So..
-9 + (-83) = -92
Answer:
Yes, because if the answer needed to be negative then the two integers have to be negative since you are adding the both to get a negative response.
Step-by-step explanation:
if it was -5 + (-5) = -10 (negative)
