Решите уравнения.
1)
4 x +1 3x - 8
--------- = --------- .
x - 3 x + 1
2)
x 3 3
------- + ------- = --------------.
x - 3 x - 2 x2 - 5x + 6
1) (4x + 1)*(x+1) = (x - 3)*(3x - 8)
4x^2+4x+x+1 = 3x^2-8x-9x+24
x^2+22x-23 = 0
x1 = 23, x2 = -1
(4х+1)(х+1) = (х-3)(3х-8)
4х^2+5х+1=3х^2-17х+24
D= 5^2 - 4 * 4*1=25-16= 9
х1= -1/4 , х2 = -1
со вторым так же))
D= 1 х1= 3, х2= 2 2/3
