Respuesta :

Answer:

Hello!The answer would be D-(x-8) and (x-3)

Step-by-step explanation:

Your welcome :)

The factors of the function, If the zeros of a quadratic function are 3 and 8 will be (x - 3) and (x + 8), i.e. option D.

What is quadratic function?

Quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero.

We have,

Zeros of a quadratic function are 3 and 8,

Now,

Let,

[tex]\alpha = 8[/tex] and [tex]\beta=3[/tex]

So,

Now,

Using sum of zeros and product of zeros,

i.e.

[tex]\alpha+\beta=8+3=11[/tex]

And,

[tex]\alpha *\beta =8*3=24[/tex]

So,

The quadratic equation will be in form of ,

[tex]x^2-(\alpha+\beta)x+\alpha\beta=0[/tex]

i.e.

[tex]x^2-(8+3)x+24=0[/tex]

i.e.

[tex]x^2-8x-3x+24=0[/tex]

taking common,

x(x + 8) - 3(x - 8) = 0

(x - 3) (x + 8) = 0

So,

The factor of the quadratic equation are (x - 3) and (x + 8).

Hence, we can say that the factor of the quadratic equation are (x - 3) and (x + 8), i.e. option D.
