Step-by-step explanation:
<u>Standard Form of Quadratic Function</u>
The standard form of a quadratic function is:

where a,b, and c are constants.
The factored form of a quadratic equation is:

Where
and
are the roots or zeros of f, and a is constant.
We know the zeros of the function are 1 and -10. The function is:


Operating:

Joining like terms:

Since we are not given any more restrictions, we can choose the value of a=1, thus. the required function is:

3.4+0.4+4.17=7.97 you just have to try different combinations of different numbers with the decimals.
