Let's say y1, y2, and y3 are zeros. Set up an expression like this (x-y1)(x-y2)(x-y3) [This is factored form] and then multiply carefully. That works with any number of roots. If 0 is a root, add an x by itself to the beginning of the factored form expression. Also, imaginary roots come in twos. Therefore, if given i as a root, you need (x-i)(x+i). If you have something in x + yi form for a root, you'll need the complex conjugate. That would make (x-(a+bi))(x-(a-bi))

How do you find the zeros of cubic polynomial equation?
If the cubic polynomial you are given does not have an obvious factorization, then you must use synthetic division. I'm sure wikipedia can tell you all about that.
How do we find all real numbers in a equation?
You solve the equation.
Which of thw following points are on the line given by the equation y equals -3x plus 5?
(1,2) (0,5) (-1,8) (2,-1) (-2,11) All of these are solutions to the given equation.
How do you graph quadratics by finding zeros?
You cannot graph quadratics by finding its zeros: you need a lot more points.Some quadratics will have no zeros. Having the zeros does not tell you whether the quadratic is open at the top (cup or smiley face) or open at the bottom (cap or grumpy face). Furthermore, it gives no indication as to how far above, or below, the apex is.
How many zeros does 7500 billion dollars have?
7500 followed by 9 zeros; that is 75 followed by 11 zeros in all

How do you find the zeros in an equation by looking on a graph?
They are all the points where the graph crosses (or touches) the x-axis.
How do you find all the zeros of a function?
You could try setting the function equal to zero, and finding all the solutions of the equation. Just a suggestion.
How do we find all real numbers in a equation?
You solve the equation.
What is a solution set?
is a set of all replacements that make an equation time in mathematics solution set is set of values which satisfies a given equation. For solving solutions you can get help from online Find Math Solutions.
How do you get a solution set?
The solution set for a given equation is the set of all points such that their coordinates satisfy the equation.
What is the answer Find all the zeros of x3-5x2-x plus 5?
They are -1, 1 and 5.
Which of thw following points are on the line given by the equation y equals -3x plus 5?

Is 3.01 equivalent to 3.010?
yes. technically all decimals have an infinite amount of zeros behind them. you just have to apply significant digits to find how much zeros you are suppose to write.
