One of Marianna's homework problems was to solve the equation below.
Strike441 [17]

Answer:

<h2>Marianna is incorrect because x2</h2><h2>2x13 can be factored into two binomials</h2>

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

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

<u>x=-2</u>
