divide by 3. (x+2) (x-2) = 0 set both equal to 0 x= -2 and x= 2
Negative plus a negative is a negative. Ex. -1+-1=-2 Negative times a negative is a positive. -2*-2=4 But a negative [minus] plus a positive [plus] can be minus, zero or plus: For example, -3 + 2 = -1 -3 + 3 = 0 -3 + 4 = +1
6-2 = 4
x2 - x - 2 = 0(x - 2)(x + 1) = 0x = 2 and -1
No. 7b - 2b = 5b
it doesn't it equals 4
Yes, it is.
=1
0 minus negative 6 is equal to 6.
0
2/3-2/3=0
-6
so, if 2 minus Ln times 3 minus x equals 0, then 2 minus Ln times 3 equals x, therefore 2 minus Ln equals x divided by three, so Ln + X/3 = 2 therefore, (Ln + [X/3]) = 1
Nope - 9 - 0 = 9 !
divide by 3. (x+2) (x-2) = 0 set both equal to 0 x= -2 and x= 2

-10 minus -10 is 0.
