3x² - 5x - 6x - 10 = 0
(3x²-5x ) - (6x - 10) =0
x (3x - 5) - 2 (3x-5) =0
(x-2 )(3x-5) = 0
x-2 = 0 atau 3x-5 = 0
x= 2 3x= 5
x= 5/3
b. 2x² - 15 = x(x +2)
2x² - 15 = x²+ 2x
2x² - x² -2x - 15= 0
x² - 2x - 15 = 0
(x - 3 )(x-5) = 0
x-3 = 0 atau x-5= 0
x= 3 x=5
maaf kalo salah
(3x-5) (x+2)
3x-5=0 x+2=0
x2=5/3 x1=-2
b)2x²-15=x²+2x
x²-2x-15=0
(x-5) (x+3)
x-5=0 x+3=0
x2=5 x1=-3
