Not sure what you mean by "zero element". If an expression is equal to zero, and you can factor it, then at least one of the factors must be zero; this is often useful to solve an equation.
Factor it! Set each equal to zero! Solve
If you set a function equal to zero and solve for x, then you are finding where the function crosses the x-axis.
Identify your variables. Make one of the variables equal zero and solve for the other variable. Once you have a solution for this varaible this solution is called a zero. Make the other variable equal to zero and solve for the other variable. Once you have a solution for this variable this solution is also called a zero.
If there is one variable. Then put each variable equal to zero and then solve for the other variable.
Any exponent to the power of zero is simply 1, with the exception of zero itself! Zero to the power of zero has no definitive answer, though it may sometimes be taken as equal to one.
Set each factor, in turn, equal to zero and solve for x.
-- Factor the left side of the equation. -- Set one factor equal to zero, and solve it for 'x'. That gives you one solution to the equation. -- Set the other factor to zero, and solve it for 'x'. That gives you the other solution to the equation. -- If you don't get x=2 and x=-8/3 then repeat the previous steps, because you made a mistake the first time.
you have to first find the derivative of the original function. You then make the derivative equal to zero and solve for x.
Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.
No, 1 is not equal to 0. 0 is equal to 0 and 1 is equal to 1.
Equals divided by non-zero equals are equal.
