One of Marianna's homework problems was to solve the equation below.
x2 + 2x - 13 = 0
Marianna decided that the equation could not be factored, and therefore the equation
has no real solutions.
Which statement is true?

Marianna is incorrect because x2
2x13 can be factored into two binomials.

O Marianna is incorrect because x2 0 2x
13 has a greatest common factor.

Marianna is correct.

Marianna is incorrect becasue although x20 2x 13 cannot be factored, she could still use
the quadratic formula to find the two real solutions.

Answer:

Marianna is incorrect because x2

2x13 can be factored into two binomials

Step-by-step explanation:

ax^2+bx+c = 0

x=−1+√14 or x=−1−√14

discriminant=56

completing square x=−1+√14 or x=−1−√14

Now, we can solve each term for  

x=-2 she is incorrect

x(x+2)=0

Now, we can solve each term for  

0:  

x=0

- no other work needed,

and

x+2=0

x+2-2=0-2

x+0=-2

x=-2
