Can you solve Question 8?

Answer 1

Answer:

2+476'_++ please thanks My answer

Step-by-step explanation:

Thus, if a quadratic has two real roots α,β, then the x-coordinate of the vertex is 12(α+β). Now we also know that this quantity is equal to −b2a. Thus we can express the sum of the roots in terms of the coefficients a,b,c of the quadratic as α+β=−ba.
