1st strategy: Add the first two terms and the last two.
16+35 + 24+14
51 + 38 = 89
2nd strategy: add the first and last term and the middle 2 terms.
16 + 35 + 24 + 14
30 + 59 = 89

Answer:
I think it's A...
Step-by-step explanation:
It's been a little while since I've done polynomials, binomials, monomials, etc., so I think I'm right, but sorry if I'm wrong...
If the discriminant is a positive number, there will be 2 possible solutions. If you replace the entire section of b²-4ac with 16, you will see that the equation becomes; (-b+-√16)/2a --> leading to an answer with the + and another with the -.
If the discriminant is 0, there will be 1 possible solution, (again replace this into the discriminant value) (-b)/2a ---> this formula is used to also find the x coordinates of a vertex, fyi.
If the discriminant is a negative number, there will be no solution (since squareroot of a negative number is not possible)
Hope I helped :)
The answer is y-4=3[(x-(-4)]
This is because of the formula y-y1=m(x-x1)
