-3(x+2)2(x-1)>3(x-3)+2

Question

-3(x+2)2(x-1)>3(x-3)+2

Answer 1

-3(x+2)+2(x-1)>3(x-3)+2 то,

-3x-6+2x-2>3x-9+2

-4x>1

x<-1/4</strong>

x∈(-∞;-1/4)

Answer 2

-3(x+2)2(x-1)>3(x-3)+2

-6(x²+x-2)>3x-9+2

-6x²-6x+12-3x+7>0

-6x²-9x+19>0

6x²+9x-19<0</p>

D=81+4*6*19=537

x=(-9±√537)/12

(-9-√537)/12
