![Solve for x 3x2 10 5 class=](https://us-static.z-dn.net/files/d8c/c9186c6278e6eca5fb37b24e38f1aa96.png)
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]
