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.
x2 = 8xx2- 8x = 0x(x - 8) = 0x = 0 ;x - 8 = 0x = 8
It is: (-4)^2 +(-4) -9 = 3 when x is equal to -4
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

It equals x2 - 34
2x2 + x2 = 3x2
Only if x is equal to 2.
(12x6)x2 = 12x8
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.
2x2=4 x2=8 x2=16 x2 = 32 and 5x5 = 25 so no, I guess not.
x2 + x2 = 2x2 2x^2
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).
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
x2 + x2 = 48 2x2 = 48 x2 = 24 x = √24 x = 2√6
x2=6*150 x2=900 x=30
