Dear student

5x² + 2x + 9 > 3x² + 10x +7

2 x² -8x + 2 >0

x² - 4x +1 >0

Now you cam solve it by wavy curve method

5x² + 2x + 9 > 3x² + 10x +7

2 x² -8x + 2 >0

x² - 4x +1 >0

After solving through wavy curve method we get,

x belongs to (-infinity,-8-root60/2) U (-8+root60/2), infinity

2x²-8x+2>0 (as we cannot take 3x²+10x+7 directly to right hand side since we dont know its sign )

x²-4x+1>0 (by taking 2 as common and sending t to rhs)

After this we should find the roots of the above equation and use wavy curve method to get hte required answerI hope this answer helps you
