The answer is -x2.
A fuller explanation is as follows:
Where letter X is an unknown value, -1 times Xsquared ( -1 x X2 )is just a general statement about X and would be more properly written as -X2.
If we substitute say 2 as the value of X then -X2 = -2 x -2,
now both (2 x 2) and (-2 x -2) = 4
thus both -1 x X2 or -X2 = 4
From the above you can see that what "minus 1 times x squared" is equal to depends upon the value of the letter x or X as I have written it to avoid confusion with the "times" sign usually written as x.

You have to put your heart into it!
x + 1
i think the answer is 1 X2+2xX-1 X=1 x times x = 1 plus (X times x) = 1 1+1 equals 2 minus one = 1Whoever above is, is wrong. the actual answer is X^(2)+2X-1: The part showing '^(2)' means to the power of two or squared on a computer.
(x - 1)(x + 1)
x(x-1)
x = 1
(x + 1)(x - 8)
x = ? 42 = x squared minus x
-3
This expression factors as x -1 quantity squared.
