x2-8x=0
( add 8x to both sides)
x2 =8x
(divide by x)
x=8
( x2divided by x equals x)

Look at the equation a times x equals 0 What value of x makes this equation true when a is not equal to 0?
In that case, x must be equal to zero. (0)
Show that a x 0 equals 0 x a equals 0?
Yes it does equal 0. This is proved by commutative property of maths which says that 2 numbers can be multiplied in many ways.
How do you solve x equals -x?
x = -x; whence,x + x = 0; 2x = 0; and x = 0. This yields the un-surprising result that the only number that is equal to its negative is zero.
If x-6x equals 0 what is x?
x - 6x = 0-5x= 0x = 0/-5which equals x = 0
If 4 times x equals 0 what does this mean?
Obviously, X is the variable which you are trying to get alone, and 0 is what the problem should equal. Basically, you're trying to get X by itself.
What does x equal in the equation x equals -x?
x=0

Show that a x 0 equals 0 x a equals 0?
Yes it does equal 0. This is proved by commutative property of maths which says that 2 numbers can be multiplied in many ways.
What does 1x plus 1 plus x equals 1 equal?
x = 0
Why does x plus x equal x?
It doesn't; it equals 2x. Only if x = 0 does 2x = x.
What does x equal in y equals x squared plus 4?
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
What is the answer to this question 0 x 0?
0 times 0 equals 0. Anything times with 0 would equal 0.
How do you solve x equals -x?
x = -x; whence,x + x = 0; 2x = 0; and x = 0. This yields the un-surprising result that the only number that is equal to its negative is zero.
What does x plus 5 equals -5 equal?
0
89 plus x equals x what does x equal?
89+x=x 89=x-x 89=0 Therefore, "No solution".
Why is o raised to zero not equal to 1?
5 raised to the power 3 equals 5 x 5 x 5 = 125 a to the power of 3 equals a x a x a zero to the power 3 = 0 x 0 x 0 = 0 zero to the power 10 = 0 x 0 x 0 x 0 x 0 x 0 x 0 x 0 x 0 x 0 = 0 So you can see that no matter how many times we multiply zero by itself the answer is always zero. Hence zero raised to the power zero equals zero
If a times b equals 0 does a or b equal 0 find the exception?
In the equation a x b = 0, either a, b, or both equal zero, and there are no exceptions.
