Answer 1

Answer:

the ans is above in pic.

Answer 2

Answer:

-6/5 or 6/5

Step-by-step explanation: We are using completing squares method.

5/2y^2 + 2y=6

divide each term by 5/2

y^2 + 4/5y = 12/5

add 4/25 to both sides

y^2 + 4/5y + 4/25 = 12/5 + 4/25

(y+2/5)^2 = 60+4/25

(y+2/5)^2 = 64/25

y+2/5 =+- 8/5

y = +-8/5 - 2/5

y = -8/5 + 2/5                                              y = 8/5 - 2/5

    = -6/5                                                            = 6/5
