The solutions of a quadratic equation are 5 and -1. What is the factored form of a related quadratic function?

a
f(x) = (x + 5)(x + 1)
b
f(x) = (x - 5)(x + 1)
c
f(x) = (x + 5)(x - 1)
d
f(x) = (x - 5)(x - 5)

Respuesta :

Answer:

Step-by-step explanation: b

Option (B) f(x) = (x - 5)(x + 1) is the factored form for the quadratic function is the correct answer.

What is a factored from?

When the quadratic expression is a product of two factors where each one is a linear expression, this is called the factored form. The given number or polynomial is expressed as a product of the simplest possible form.

For the given situation,

The solution of the quadratic equation are 5 and -1.

The general form of quadratic equation is [tex]Ax^{2}+Bx+C=0[/tex]

When we equate the solution to the variable x, we can obtain the factored form of that equation.

For [tex]x=5\\[/tex]

⇒ [tex]x-5=0[/tex]

For [tex]x=-1[/tex]

⇒ [tex]x+1=0[/tex]

Thus the quadratic function can be expressed as f(x) = (x - 5)(x + 1).

Hence we can conclude that option (B) f(x) = (x - 5)(x + 1) is the factored form for the quadratic function is the correct answer.
