Answer:
a = 7/6 a = -1/5
Explanation:
30 a^2 - 7 = 29a
Subtract 29a from each side
30 a^2 -29a- 7 = 29a-29a
30 a^2 -29a- 7 = 0
Factor
( -7 ) ( +1) =0 to get -7
We need to determine what goes in the first part
5*7 = 35 - 6 = 29
( 6a -7 ) ( 5a +1) =0
Using the zero product property
6a -7 =0 5a+1 =0
6a = 7 5a = -1
a = 7/6 a = -1/5
