e2x=ex^2 basically means that x2=2x, in which case x2-2x=0, x = 0, 2.
I don't think that's what the question meant. It could mean: e2x=(ex)2 . Which comes from one of the rules of exponents. Basically, look at it this way:
Take the natural log of both sides: ln e2x= ln(ex)2
From rules of logs:
(2x) ln e = (2) ln ex
2x ln e = (2) (x) ln e
2x = (2)(x)
-2y square exp power -2x-1
Because you are just adding the same variable to itself, the variable does not change. in the same way that 2 + 2 is 4, 2x2 + 2x2 is 4x2.
No. x squared is x times x, whereas 2x is x + x.

It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3
2x1 = 2x
-2 to the 4th power is 16.
To find the product of x squared and 2x squared, you multiply the coefficients (2 and 1) to get 2, and then add the exponents of x (2 and 2) to get x to the power of 4. Therefore, x squared times 2x squared is equal to 2x^4.
only when x is equal to 2
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
When writing a polynomial, the term with the highest power usually goes first: 2x2+2x The 2x squared goes first.
x2 + x2 = 2x2 2x^2
If it were any other power other than zero, then we'd have to know what 'x' is. But anything to the zero power is ' 1 '.

2x2 + x2 = 3x2
x2 - 2x = x(x-2) and that cannot be simplified further.
This expression factors as x -1 quantity squared.
