Question

One of Marianna's homework problems was to solve the equation below.

Answer 1

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
