Find all real solutions of the equation, approximating when necessary.

x2 + 4x + 10x+15 = 0

a. X8 2.426

c. 78 5.128

b. XX-2.426

d. X8 - 5.128

id say b XX-2.426

Step-by-step explanation:

will if u add all the xs toghether depending on what grade ur in it would probly be 16+15=0 but thats not one of the answers so you would have to simplify it or i shoud say solve it differently
