5a^2 - 44 = 81

Add 44 to both sides:

5a^2 = 125

Divide both sides by 5:

a^2 = 25

Take the square root of both sides:

a = 5

Answer:

x = ± 5

Step-by-step explanation:

Given

5a² - 44 = 81 ( add 44 to both sides )

5a² = 125 ( divide both sides by 5 )

a² = 25 ( take the square root of both sides )

a² = ± [tex]\sqrt{25}[/tex] = ± 5

That is x = - 5 or x = 5
