Question

Find the sum and product of the roots. 3x 2 - 4x - 7 = 0

Answer 1

a. sum = -4/7, product = -7/3
b. sum = 4/3 product = -7/3
c. sum = -4, product = -7
d. sum = 3/5 , product =7/3

Answer 2

Divide by 3

\(x^{2} - (4/3)x - 7/3 = 0\)

Ponder this:

\((x-a)(x-b) = 0\)

\(x^{2} - (a+b)x + ab = 0\)
