Answer 1

-9/7, 3/8

Explanation:

The zeroes can be found in the parenthesis.

You need to set each parenthesis to zero first.

7x+9=0

subtract 9

7x=-9

divide 7

x=-9/7

For 8x-3=0

add the 3

8x=3

divide the 8

x=3/8

Answer 2

hello :- 9/7 and 3/8

Explanation:

y = 6(7x + 9)(8x – 3)

y=0 means : 7x+9=0 or 8x-3=0

7x = -9 or 8x=3

x= - 9/7 or x= 3/8
