Sum and Product of Roots

ax² - 3x - c = 0
Given the sum and product of roots are 6 and -9 respectively. What are the values of a and c?

• a = 1/2
  c = 9/2

• a = - 1/2
  c = - 9/2

• a = - 1/2
  c = 9/2

• a = 1/2
  c = - 9/2

-2x² - 5x + 1 = 0
What are the sum and product of roots?

• Sum = 5/2
  Product = 1/2

• Sum = - 5/2
  Product = - 1/2

• Sum = - 5/2
  Product = 1/2

• Sum = 5/2
  Product = - 1/2

2x² - 6x - 7 = 0
What are the sum and the product of roots?
