Add 10 to both sides

3x^2 = -5 + 10

Simplify -5 + 10 to 5

3x^2 = 5

Divide both sides by 3

x^2 = 5/3

Take the square root of both sides

x = √5/3

Simplify √5/3 to √5/3

x = ±√5/3

Answer: A. x = ±√5/3

Answer:

A

Step-by-step explanation:

given

3x² - 10 = -5 ( add 10 to both sides )

3x² = 5 ( divide both sides by 3 )

x² = [tex]\frac{5}{3}[/tex]

Take the square root of both sides

x = ± [tex]\sqrt{\frac{5}{3} }[/tex] = ± [tex]\frac{\sqrt{5} }{\sqrt{3} }[/tex]
