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
6x to the 5th power (im pretty sure)
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

No. x squared is x times x, whereas 2x is x + x.
2x1 = 2x
-2 to the 4th power is 16.
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.
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 '.
x2 + x2 = 2x2 2x^2
2x2 + x2 = 3x2
x2 - 2x = x(x-2) and that cannot be simplified further.
This expression factors as x -1 quantity squared.
2x squared can best be describe as some variable being double and then squared.
2 x cosine squared x -1 which also equals cos (2x)
