Question

Can someone tell me what I did wrong here

Answer 1

no roots.

Explanation:

1)
`√(8x+16)=2-8; \ - \ correct;`

2)
`√(8x+16)=-6; \ - \ correct;`

note, the value after operation 'square root' cannot be negative ('-6' is on the right side!), then

3) it means, the given equation has no real roots.
