Why does the square root of -25 have no real solution?
Because the square root of -25 would be that number that, squared, would equal -25. No number, positive or negative, can result in a negative square. Since -25 is a negative number, no number, positive or negative, can be squared to equal -25.
How do you factor x cubed plus 9x squared plus 2x plus 18?
Since the problem has 4 terms, first you factor x cubed plus 9x squared, then you factor 2x plus 18. So when you factor the first two term, you would get x sqaured (x plus 9). Then when you factor the last two terms and you get 2 (x plus 9). Ypure final answer would be (x squared plus 2)(x plus 9)
Factor x squared minus y squared?
( x - y )2There isn't enough information to answer this question because they have two squared variables and you do not know what is being squared. You would first need to either know the value of one of the variables and an equation of the value of both of the variables before you would be able to factor.
How would you factor 12n squared minus 18n?
6n(2n - 3)
How would you factor 2x squared plus 7x plus 6?
You would factor 2x2 + 7x + 6 into (2x + 3) (x+2)
Why does the square root of -25 have no real solution?
Because the square root of -25 would be that number that, squared, would equal -25. No number, positive or negative, can result in a negative square. Since -25 is a negative number, no number, positive or negative, can be squared to equal -25.

What does negative x squared equal if x is a neg three?
I believe it would be 9, because negative three's negative would be 9 (double negative)
What is negative 3 squared?
-3^2 = -9, It is -3 x 3 = -9, unless its in parenthesis, which would be (-3)^2, this equation is -3 x -3, which equals 9. Since a negative and a negative in multiplication is always positive.9

How would you Factor x squared - 144?
(x - 12)(x + 12)
How would you factor 12n squared minus 18n?
6n(2n - 3)
In imaginary numbers Since the symbol i squared equals negative 1 would negative i squared equal positive 1?
No.(-i)2= (-1 x i)2= (-1)2 x i2= 1 x i2= i2= -1but if it is written-i2Then= -i2= (-1) * i2= -1 * -1= 1
How would you factor 2x squared plus 7x plus 6?
You would factor 2x2 + 7x + 6 into (2x + 3) (x+2)
Can fisher information be negative?
No, Fisher information cannot be negative. It is defined as the expected value of the squared gradient of the log-likelihood function, which is always non-negative. Since it measures the amount of information that an observable random variable carries about an unknown parameter, a negative value would not make sense in this context.
Is it possible to find the square root of a negative number explain why or why not?
This is not possible, because any number squared would be positive, not negative.
How would you factor x4-2?
(x squared plus the square root of 2) times (x squared minus the square root of 2).
