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
