Solve the multi step literal equation: solve equation for A b^2A^2-3g=q

I am Lyosha [343]

Answer:

A = ± $\sqrt{\frac{q+3g}{b^2} }$

Step-by-step explanation:

Given

b²A² - 3g = q ( add 3g to both sides )

b²A² = q + 3g ( divide both sides by b² )

A² = $\frac{q+3g}{b^2}$ ( take the square root of both sides )

A = ± $\sqrt{\frac{q+3g}{b^2} }$
