Dear student
 
5x² + 2x + 9 > 3x² + 10x +7
 
2 x² -8x + 2 >0
 
x² - 4x +1 >0

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
