Answer 2

Answer:

Step-by-step explanation:

35y²+12/y²=44

Replacing y² by a

35a+12/a=44. Taking LCM on Lhs

35a²+12=44a

35a²+12-44a=0

35a²-44a+12=0

Product=35×12=420

Sum=44

35a²-(14+30)a+12=0

35a²-14a-30a+12=0

7a(5a-2)-6(5a-2)=0

(7a-6)(5a-2)=0

7a-6=0

a=6/7

y²=6/7

y=+√6/7, y=-√6/7

5a-2=0

a=2/5

y²=2/5

y=+√2/5, y=-√2/5
