- If 3X - 1 equals what is the value of X2 plus X?
- If 3X - 1 = 11, what is the value of X^2 + X?
What is x2 81y2 equal to?
x2 - 81y2 = (x + 9y) (x - 9y)The actual numerical value depends on the values of 'x' and 'y'.
What is minus 1 times x squared?
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) = 4thus both -1 x X2 or -X2 = 4From 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.
