To solve the equation, we need to isolate the radical term on one side of the equation.
Starting with the given equation:
3√(5x^2 - 10) + 7 = 4
Subtracting 7 from both sides:
3√(5x^2 - 10) = -3
Dividing both sides by 3:
√(5x^2 - 10) = -1
To eliminate the square root, we need to square both sides of the equation:
(√(5x^2 - 10))^2 = (-1)^2
5x^2 - 10 = 1
Adding 10 to both sides:
5x^2 = 11
Dividing both sides by 5:
x^2 = 11/5
Taking the square root of both sides:
x = ±√(11/5)
So, the two solutions are:
x = √(11/5)
x = -√(11/5)

3√(5x^2 - 10) + 7 = 4
