Question

The sum of roots of (a+beta) is............ a)-b/a
b)b/a
c)-c/a
d)c/d​

Answer 1

Answer:

A)-b/a

Step-by-step explanation:

thus,of a quadratic has two real roots a,b,then the x-coordinate of the vertex is 12(a+b). ....now what 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 a+b=-ba
