Each factor will contribute a zero. f(x) = Ax^2 + Bx + C will take the form of something like f(x) = (x-r1)(x-r2) when you factor it. Now the zeros are the values of x for which f(x) = 0. You know 0 times anything is zero, so consider one factor at a time. (x-r1) will equal zero when x = r1, therefore r1 is a "zero" (or "root") of f(x). Incidentally, f(x) = 0 when x = r1 because 0*(x-r2) = 0 for any value of r2.
To find the second "zero" find the value of x that makes (x-r2) equal zero.
If f(x) = (x+2)(x+3) then the zeros are -2 and -3, because f(-2) = 0 and f(-3) = 0.
So if you can factor a function, you can easily find its zeros. The challenge is actually factoring the function.

How can you use a graph to find zeros of a quadratic function?
The zeros of a quadratic function, if they exist, are the values of the variable at which the graph crosses the horizontal axis.
How do you find the zeros of any given polynomial function?
by synthetic division and quadratic equation
What are the zeros of a polynomial function?
the zeros of a function is/are the values of the variables in the function that makes/make the function zero. for example: In f(x) = x2 -7x + 10, the zeros of the function are 2 and 5 because these will make the function zero.
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.
Where can one find Independent Factoring Brokers?
The Independent Factoring Brokers Association is headquartered in the United Kingdom. There is no regulation regarding factoring brokers thus anyone can call themselves a factoring broker and provide advice.
How do you find the zero in a function?
To find the zero of a function, set the function equal to zero and solve for the variable. This typically involves rearranging the equation and can include factoring, using the quadratic formula, or applying numerical methods if necessary. Graphically, the zero corresponds to the points where the graph of the function intersects the x-axis. Analyzing the function's behavior can also help identify potential zeros.
How can you use the zeros of a function to find the maximum or minimum value of the function?
You cannot. The function f(x) = x2 + 1 has no real zeros. But it does have a minimum.
How can you use a graph to find zeros of a quadratic function?
The zeros of a quadratic function, if they exist, are the values of the variable at which the graph crosses the horizontal axis.
Use the graphing calculator to graph and find the zeros of the function y 2x2 plus 0.4x and ndash 19.2. The zeros of the function are?
To find the zeros of the function ( y = 2x^2 + 0.4x - 19.2 ), you can use a graphing calculator to graph the equation. The zeros are the x-values where the graph intersects the x-axis (where ( y = 0 )). By using the calculator's zero-finding feature, you should find the approximate values for ( x ). The zeros of the function are the solutions to the equation ( 2x^2 + 0.4x - 19.2 = 0 ).
How do you find the real zeros of a cubic function without a calculator?

What does it mean to find the zeros of a function?
The zeros of a function are the values of the independent variable where the dependent variable has value of zero. In a typical representation where y = f(x), the zeroes are the points x where y is 0.
What are integral zeros?
The integral zeros of a function are integers for which the value of the function is zero, or where the graph of the function crosses the horizontal axis.
