Question

Uprość wyrażenie wymierne :

x^{2}-5x+6 : 2x^{2}-5x-3=

Answer 1

(x²-5x+6):(2x²-5x-3)=(x-2)(x-3):2(x+0,5)(x-3)=(x-2):2(x+0,5)

 

 

x²-5x+6                                    2x²-5x-3

 

Δ=25-4·6=1    √Δ=1                 Δ= 25-4·(-3)·2=49     √Δ=7

x=5-1/2=2                               x=5-7/4=-0,5

x=5+1/2=3                              x=5+7/4= 3

Answer 2

=(x-2)(x-3) : (2x+1)(x-3)=
=(x-2) : (2x+1)
