solutions of the equation: x2-x=20
You mean this x2?
x2 + 5x - 6x = x2 - x = x(x - 1) which is zero when x = 0 or x = 1
1 over x2 - 4 is the multiplicative inverse of x2 minus four 1/x2 - 4
Write it as x2 - 2x - 4 = 0, and solve with the quadratic formula (a = 1, b = -2, c = -4).

1/x2 or x-2
1 over x2 - 4 is the multiplicative inverse of x2 minus four 1/x2 - 4
Write your answer in descending powers of x. (x2 + 3x + 1)(x2 + x + 2)?Please give this person the answer someone.Thanks...:)
There is not a way to cheat on FFX X2. This is a game.
Write it as x2 - 2x - 4 = 0, and solve with the quadratic formula (a = 1, b = -2, c = -4).
2/x + 1/x2 = (2x+1)/x2
Assuming you mean x2...Simply type x2, then highlight the 2, and select Format, then Character, then Position and select superscript. this will move the 2 upwards, and reduce the point size.
In order to combine terms, the variable(s) must be the same and the exponent(s) must be the same on the variables. Since you have an x2 term, x term, xy term and y term, none of the terms can be combined. So, the answer is: x2 + 4x + xy + 4y. The only thing you could do in this problem is to factor out a 4 from the 4x & 4y so another way to write this is: x2 + xy + 4(x + y).
