Question

plz help.. plz solve this​

Answer 1

Answer:

Step-by-step explanation:

is the quadratic equation = 0

sum of zeros = 2/3+2/3 = -coefficent of x/ coefficent of x²

                       4/3 = -7/a

                  4a = -21

                  a =-21 /4

now the product = 2/3 x 2/3 = 4/9 = constant term/coefficent of x²

                    4/9 = b / a

                    b= 4/9 x 4/-21

                    b = -16/189
