If the roots of the quadratic equation ax^2 + bx + c = 0 are p and q, what is the relationship betwe

A. p + q = -b/a and pq = c/a

B. p + q = c/a and pq = -b/a

C. p - q = -b/a and pq = c/a

D. p + q = b/a and pq = c/a

E. None of the above

Answer: A. p + q = -b/a and pq = c/a

According to Vieta's formulas, the sum of the roots p + q is equal to -b/a and the product pq is equal to c/a.
