∙ 12y agox2 - x2 = 0.
This will always equal 0. It does not matter what the value of the variable "x" is. If you subtract an amount from an equal amount then this will leave 0.

What is the solution to the inequality x2 equals 16?
If x2 = 16 then this is not written as an inequality.An inequality tells us that one thing is not equal to another.The above is an equation, because it is telling us that one thing is equal to another.If x2 = 16 then x = 4 & -4.
Why does x equal to 8 and 0 in x2 equals 8x?
x2 = 8xx2- 8x = 0x(x - 8) = 0x = 0 ;x - 8 = 0x = 8
What is the correct evaluation of x2 plus x - 9 when x is equal to -4?
It is: (-4)^2 +(-4) -9 = 3 when x is equal to -4
What is x squared-7x equals 8 factored?
x2 - 7x = 8 x2 - 7x - 8 = 0Now find two numbers that multiply to equal -8, and add to equal -7.(1) * (-8) = -8(1) + (-8) = -7(x+1)(x-8) = 0 This is the factored form of x2 - 7x = 8You can then solve the equation if necessary, and get:x = -1 or x = +8
X to the power of 2?
x to the power of 2 is equal to x times x (x squared). This is written as x2.
What does x2 plus 6-40 equal?

Is x2 equal to 2x?
Only if x is equal to 2.
What is in brackets12 x 6 end bracket x2 equal?
(12x6)x2 = 12x8
What the derivetive of x2?
Any monomial in the format: axn has a derivative equal to: nax(n - 1) In this case, "a" is equal to 1 and "n" is equal to 2. So the derivative of x2 is equal to 2x.
Are 2x2x2x2x2 and 5x5 equal?
2x2=4 x2=8 x2=16 x2 = 32 and 5x5 = 25 so no, I guess not.
What is X squared plus x squared equal to?
x2 + x2 = 2x2 2x^2
Can variables with exponents that are being multiplied be combined?
You can combine like variables but not unlike variables.So, for example, x2 * x2 = x4 but x2 * y2 does not equal xy4!Let's make x equal 2 and y equal 3 just to demonstrate this.So if x2 * x2 = x4 then 22 * 22 = 24 which would mean 4 * 4 = 16 (Yes, that's right)But x2 * y2 can not be combined. 22 * 32 = 4 * 9 = 36 (which is not equal to a combination of x and y to the power 4).
What is a number sentence stating that 2 amounts are equal?
x = x, y=y, x2=x2

x2+xx = 15 Which is the same as: x2+x2 =15 2x2 = 15 x2 = 7.5 x = the square root of 7.5
What is x squared plus x squared equal to 48?
x2 + x2 = 48 2x2 = 48 x2 = 24 x = √24 x = 2√6
What will x equal if its multiplied by itself?
