Answer:
Pretty sure its coefficient
Step-by-step explanation:
Answer:
x = ± 
Step-by-step explanation:
Given
+
= 1
Multiply through by a²b² to clear the fractions
b²x² + a²y² = a²b² ( subtract a²y² from both sides )
b²x² = a²b² - a²y² ( divide both sides by b² )
x² =
( take the square root of both sides )
x = ±
