Tolong jawab setengah lagi yah no 1 bagian (E,F,G) sama langkah-langkahnya kak.
E. 2y² – 5y – 3 = 0
(2y + 1)(y – 3) = 0
2y + 1 = 0
2y = -1
y = -1/2
y – 3 = 0
y = 3
maka, y = -1/2 dan y = 3
F. y² + 4y – 5 = 0
(y + 5)(y – 1) = 0
y + 5 = 0
y = -5
y – 1 = 0
y = 1
maka, y = -5 dan y = 1
G. -t² + 3t + 4 = 0
t² – 3t – 4 = 0
(t + 1)(t – 4) = 0
t + 1 = 0
t = -1
t – 4 = 0
t = 4
maka, t = -1 dan t = 4
