Given : 14y²-6y+8/10y²+4y+7 = 7y-3/5y+2
To Find : Check its true or not
Solution:
y²-6y+8/10y²+4y+7 = 7y-3/5y+2
cross multiply
=> (y²-6y+8) (5y+2 ) =(10y²+4y+7)(7y - 3)
=> (y²-6y+8)5y + (y²-6y+8)2 = (10y²+4y+7)7y - (10y²+4y+7)3
=> 5y³ - 30y² + 40y + 2y² -12y + 16 =70y³ + 28y² + 49y - 30y² - 12y - 21
=> 5y³ - 28y² + 28y + 16 =70y³ -2y² + 37y - 21
=> 65y³ + 26y² + 9y - 37 = 0
Hence LHS ≠ RHS
so this is not true
