To solve the equation 3x² - 3x½ = 8, we need to first simplify it by rewriting x½ as √x.
3x² - 3√x = 8
Now we can rearrange the equation to have one side equal to zero.
3x² - 3√x - 8 = 0
This is a quadratic equation in terms of x², so let's make a substitution to simplify it further.
Let's say y = √x. Then y² = x.
Now we can rewrite the equation:
3y⁴ - 3y - 8 = 0
This equation is more manageable. Unfortunately, it cannot be solved exactly using elementary methods. We could use numerical methods like Newton's method or trial and error to find approximations of y, and then find the corresponding x values.
However, as no specific solution is requested, we'll leave the equation as it is.
