Any quadratic equation method​

Answer 1

124-12y+12+36y-18-40=0

124-46+ 36y-12y=(+12+-18+-40=-46)

98+24y=0

24y=-98

y=-98/24

y=-49/12

Answer 2

Answer:

(124-12y)2-(16-48y+24)-40=0

(248-24y)-(16-48y+24)-40=0

248-24y-16+48y-24-40=0

48y-24y+248-16-24-40=0

64y+168=0

64y=-168

y=-168/64

y=-21/8
