If 'x' is more than 1, then x2 is more than 'x'.
If 'x' is less than 1, then x2 is less than 'x'.
x2 - 15 = 2x x2 - 2x - 15 = 0 x2 - 2x - 15 = (x - 5)(x + 3) x = 5, -3
if you are doing algebra you have to have a number on the other side of the equal sign so x2-6 has to have a equal sign to figure out 6 is less than x cubed if x is greater than the cube root of 6. The answer is "true" or "false" depending on x
it may equals (n-2)(n+2)
Find the value of X in the problem 2X = 16. Solving for X will give you _______.But you don't really want the value of X multiplied by 2 giving you 16. Instead you want the value that's less than or greater than 16. So the answer would really be ± your value of X from above.
The answer would be 3x if 'X2' is '2x', but if 'X2' is x2, then the total answer would be x2 + x.
If x2 < 25 Then: |x| < 5 -5 < x < 5
(x - 2)(x + 3) = x2 + 3x - 2x -6 = x2 + x - 6
That factors to (x - 6)(x + 3) x is less than or equal to -3, 6
x2-2x = 15 x2-2x-15 = 0 (x-5)(x+3) = 0 Therefore: x = 5 or x = -3
When x is a number between -1 and 0. For example, if x=-0.5: x < x3 < x2 because -0.5 < -0.125 < 0.25
x2 - 15 = 2x x2 - 2x - 15 = 0 x2 - 2x - 15 = (x - 5)(x + 3) x = 5, -3
It depends on whether the number being raised to the power is greater than or less than 1. If x < 1 then x3 < x2 If x > 1 then x3 > x2 with equality at x = 1
You don't. There's no question there, and nothing that needs solving. "16 less than x squared" is written as (x2 - 16)
Call the numbers: x, (x+1), (x+2) Product of the smaller two: x(x+1) = x2 + x Square of the largest number: (x+2)2 = x2 + 4x + 4 Product of the smaller two is 40 less than the largest one squared: (x2 + x) = (x2 + 4x + 4) - 40 x2 + x = x2 + 4x - 36 0 = 3x - 36 0 = x - 12 x = 12 x+1 = 13 x+2 = 14 Check: Product of the smaller two = (12)(13) = 156 Square of the largest = 196. 156 is in fact 40 less than 196.
No because its discriminant is less than zero
There are no solutions because the discriminant is less than zero
It can't be factored because its discriminant is less than zero
