To be honest I just know that #1 is 143 (I think)
Answer:
f(x)=x^2+9x-10
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:

Answer:
90
Step-by-step explanation:
Multiple the number of all your options.
6 x 3 x 5 = 90
X^4 + 8x^2 - 9
= (x^2 + 9)(x^2 - 1)
= (x^2 + 9)(x + 1)(x - 1) Answer
