36q² − 64 = 0
=> 36q² = 0 + 64
=> 36q² = 64
=> q² = 64/36
=> q² = 16/9
=> q = √(16/9)
=> q = √16/√9
=> q = ± 4/3
Answer:
q =±4/3
Step-by-step explanation:
Add 64 to each side
36q² =64
Divide each side by 36
36q² /36 =64/36
q² =64/36
Take the square root of each side
sqrt(q²) =± sqrt(64/36)
q = ±8/6
