-x3 = -6
Divide both sides by -1
x3 = 6
Cube root both sides
x = 1.817120593
x> -1
If you mean ((-2) x (-6)) - (3 x (-21)) then it equals 75. Hope this helps!
One because if x3 = 1 then x must equal 1
x3-4=2 Add four to both sides. x3=6 Take the cu=6 be root of both sides. x is equal to the cube root of 6, or approximately 1.81712.
cube root of 216 = 6 > X= 6
2+4 (which equals 6) x3 (equals 18) +1 = 19
X3 - 4 = 2 X3 = 6 X = 61/3 X = about 1.817
I believe the converse is: if 2x equals 6 then x equals 3 inverse: if x doesn't equal 3 then 2x doesn't equal 6 contrapositive: if 2x doesn't equal 6 then x doesn't equal 3
Equals 6
x5 - 2x4 - 24x3 = 0 x3(x2 - 2x - 24) = 0 x3(x2 + 4x - 6x - 24) = 0 x3(x - 6)(x + 4) = 0 x = {-4, 0, 6}
3 + 2 + 25*3 - 6 = 3 + 2 + 75 - 6 = 74
-2
p x = 20 x5 - 20 x4 + 24 x2 q x = 4 x2 p = 20 x4 - 20 x3 + 24 x, if xis not equal to 0 p / qx = ( 20 x4 - 20 x3 + 24 x) / (4 x2) = (5 x4 - 5 x3 + 6 x) / x2 So p / qx = 5 x2 - 5 x + 6/x if x is not equal to 0
