Answer:

x=5, x=-5

Step-by-step explanation:

3x²-75=0

Add 75 to both sides;

3x²-75+75=0+75

Simplify;

3x²=75

Divide both sides by 3

3x²/3=75/3

Simplify;

x²=25

x=√25, x=-√25

√25=5

-√25=-5

x=5,x=-5

Hope this helped!!!

Answer:

3x² - 75 = 0

3x² = 75

x² = 75 ÷ 3

x² = 25

x = √25

x = 5
