Answer:
Yes
Step-by-step explanation:
For this case we have that by definition, the quadratic formula is:
A quadratic equation is of the form:

Option A: This equation can be solved without the quadratic formula

Option B:
This equation is not as easy to solve by factoring or as option A. We can use the quadratic formula.
Option C:

Similarly, this equation can be solved with the quadratic formula
Option D:

In this factored equation we can see that the roots are

Answer:
Option B, C
Answer:
-17
Step-by-step explanation:
you have -3(y+2)2-5+6y so first you need to distibute
=−6y+(−12)+(−5)+6y <----- distributed version
then start combining like terms
(-6y+6y)+(-12+(-5))
after you have combined those you get
-17
It's just -5-20-49 so the answer would be -74
