sq rt (-2) + (sq rt 3))2 + (-2)2
= i(sq rt 2) + 7 = 7 + i(sq rt 2) answer
this is a complex number, it cannot be further simplified.

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.
Not in real numbers. It can be factored to (x - 5i)(x + 5i) where i is the square root of negative one.
negative b plus or minus the square root of b squared minus 4AC all over 2 A
x2 + 4 = 0 then get the x on one side. x2 = -4 then find the square root of both which would cancel the square on the x. therefore the answer is: x = the square root of -4 = i squared root 4, which is a complex number ( imaginary number) since you cannot find the square root of oa negative number
(x - i)(x + i) where i is the imaginary square root of negative one
-7.. square root cancels out square

If a is any number, then a squared = (-a) squared, so one might say that a and -a are both square roots of a squared. However, the square root symbol always means the positive square root.
Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. This can be taken into squaring and square roots to infinity and still equal c, as long as there is the same number of squaring and square roots in the problem. Since this question asks for a and b squared three times, and also three square roots of a and b both, they equal c. Basically, they cancel each other out.
It's the square root of a2+b2. It cannot be simplified. It is NOT a+b. The answer is c square.
Square root of s, or negative square root of s.
X + y
Yes.
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.
(x squared plus the square root of 2) times (x squared minus the square root of 2).
Not in real numbers. It can be factored to (x - 5i)(x + 5i) where i is the square root of negative one.
