If by 3 0 you mean 3º: Any number, except 0, to the 0 power equals 1.
For example: 1 = 9/9 = 3²/3² = 3²-² = 3º = 1
To divide 3² by 3², subtract exponents.
By extension xª/xª = xº = 1, x <> 0
"<>" signifies "is not equal to" since it means "is less than or greater than" and therefore not equal to

The answer is 0. For example, 1/3 - 1/3 = 0/3 which is equal to 0.
Minus 1 times 0 plus 3 divided by 3 is equal to 1
2 x 2 + x - 1 = 0 4 + x - 1 = 0 4-1 + x = 0 3 + x = 0 3 + x - 3 = 0 - 3 x = -3 ---------- Another Solution Method (including text) for: 2 * 2 + x - 1 = 0 1. Do simple operations (*/+-) within from left to right: 2 * 2 + x - 1 = 0 4 + x - 1 = 0 3 + x = 0 2. Group like terms: - move numerical terms from the left side of the equal sign to the right side of the equal sign (remember to change the sign when moving from the left to the right of the equal sign): 3 + x = 0 x = 0 - 3 3. Do simple operations (^*/+-): x = 0 - 3 x = - 3
if you look on at this. 3^2=9 3^1=3 3^0=1 it's dividing by 3 every time so the answer for 3^0 =1
If you mean: (3x-1)(x+1) = 0, then it is 3x squared+2x-1 = 0. Its solutions are: x = 1/3 or x = -1.
