tolong selesai in donkkk

1. x^2 + 3x - 18 = (x-3)(x+6) =0
   jadi, x=3 atau x= -6
2. x^2 -8x + 15 = (x-3)(x-5) = 0
   jadi, x = 3 atau x = 5

1. a) x² + 3x - 18 = 0
(x + 6)(x - 3) = 0
x = - 6 atau x = 3

b) x² - 8x + 15 = 0
(x - 3)(x - 5) = 0
x = 3 atau x = 5

2) a) 3m(m - 2) = 2(m + 5) - 9m
3m² - 6m = - 7m + 10
3m² + m - 10 = 0
(3m - 5)(m + 2) = 0
m = 5/3 atau m = - 2
