The answer would be 3x if 'X2' is '2x', but if 'X2' is x2, then the total answer would be x2 + x.
x2 - 81y2 = (x + 9y) (x - 9y)The actual numerical value depends on the values of 'x' and 'y'.
x=5/2 or 2.5
this is what type of question? value of x? difference of 2 squares? factoring?
"x2 = 100" is an equation which, if solved for x, will give you two possible value: 10 and -10.
3x-1=11 3x = 12 x = 4 Then, x^2 +x = 20.
The answer would be 3x if 'X2' is '2x', but if 'X2' is x2, then the total answer would be x2 + x.
if x2 = 5 the value of x has to be 5 divided by 2 which is 2.5 x = 2.5
X = 8 x2 (8)2 = 64 ====
2
If x = 8 then x2 = 82 = 8 x 8 = 64
The value of x2+7x+10 depends on the value of X. If x=1, then x2+7x+10 = 18 If x=2, then x2+7x+10 = 28 If x=3, then x2+7x+10 = 40 and so forth
The LCM is the absolute value of x.
x= x2/x= x
- If 3X - 1 = 11, what is the value of X^2 + X?
x2 - 81y2 = (x + 9y) (x - 9y)The actual numerical value depends on the values of 'x' and 'y'.
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.
