If the square root of x equals 6 minus x which is the value of x?
VangelisMichaelides
x=2
22=6-2
4=4
Nop! Square root of x - not x squared!
sqrt(x) = 6 - x => |x| = (6 - x) * (6 - x) <=> |x| = 6 * 6 - 12 * x + x * x =>
=> x = 9.

How do you solve for x when it equals the square root of y to the fourth minus y?
If x equals the square root of ...., then you already have solved for x
What is a square root of a square?
Plus or minus the base. If the base is X and you square it, you get X2. If you take the square root of that, you get Plus or Minus X. This is because X*X equals X2 and -X*-X also equals X2.
What number must you add to complete the square x2 plus 16x equals -7?

What times itself equals minus?
In order to represent the square root of a minus number (which does not in fact actually exist other than as an abstract notion), mathematicians use an imaginary number called "i". i represents the value of the square root of -1. We must remember that it is not a real number, which is why we call it imaginary.So to answer your question, i, or a multiple of i, times itself equals a minus number.For example 2i * 2i = -4 (this is because we can rewrite -4 as 4 * -1. The square root of 4 is 2 and the square root of -1 is i. Therefore the square root of -4 is 2i).
Can you solve x squared minus 4x minus 2 equals 0?
Yes and x = 2+square root of 6 or x = 2-square root of 6

p=9
Does the square root of 2 or 1.5 have the greater value?
Since the square root of a number is the "number times itself that equals the original number," it makes sense that the larger the original number, then the larger the square root. The value of the square root of 2 will be greater than the value of the square root of 1.5.
