Answer:


h=x^2-12x+35

Step-by-step explanation:

Since
x=5 is the solution to
x-5=0 and
x=7 is the solution to
x-7=0, then we multiply the two expressions to get our quadratic function:


h=(x-5)(x-7)\\\\h=x^2-12x+35

Final answer:

To create a quadratic function h with zeros of 5 and 7, use the formula h(x) = k(x - 5)(x - 7) and choose k = 1 for simplicity. This gives the function h(x) = x² - 12x + 35.

Step-by-step explanation:

To write a quadratic function h with zeros of 5 and 7, we need to use the fact that if a function has zeros at x = a and x = b, then the function can be represented by h(x) = k(x - a)(x - b), where k is a non-zero constant coefficient.

In this case, the zeros are 5 and 7, so we have:

h(x) = k(x - 5)(x - 7)

We can choose any non-zero value for k, but common practice is to set k = 1 for simplicity unless given a specific leading coefficient.

Therefore, the quadratic function with these zeros is:

h(x) = (x - 5)(x - 7) = x² - 12x + 35
