To solve this equation:
(2x + 5x) sqrt(2x) - 3 = 07x sqrt(2x) - 3 = 07x * sqrt(2x) = 3sqrt(2x) = 3 / 7x
Square both sides to eliminate the square root:
2x = (3 / 7x)^22x = 9 / 49x^298x^3 = 998x^3 - 9 = 0
Now, you can solve for x using the cubic equation above.
To solve this equation:
(2x + 5x) sqrt(2x) - 3 = 0
7x sqrt(2x) - 3 = 0
7x * sqrt(2x) = 3
sqrt(2x) = 3 / 7x
Square both sides to eliminate the square root:
2x = (3 / 7x)^2
2x = 9 / 49x^2
98x^3 = 9
98x^3 - 9 = 0
Now, you can solve for x using the cubic equation above.
