Answer:

The sentence contains an error

The error is that the values of x are incorrect

Step-by-step explanation:

Given

[tex]Expression: x^2+13x+36[/tex]

[tex]Factors: (x + 4)\ and\ (x + 9)[/tex]

[tex]x = 4\ or\ 9[/tex]

Does the statement have an error? Yes, it has.

Where?

Given that the factor are:

(x + 4) and (x + 9)

Equate these two to 0

[tex]x + 4 = 0[/tex]   or    [tex]x + 9 = 0[/tex]

[tex]x = -4[/tex]  or    [tex]x = -9[/tex]

The correct values of x are in contrary to what is given in the statement

Hence;

The error is that the values of x are incorrect
