Answer 1

3) $9 x^{3} -9 x^{3}-18x>13-17x$
$-18x+17x>13$
$-x>13$
$x<-13$
4)$10x-5-12 x^{2} +6x-9x+12 x^{2} -3+4x leq 3$
$11x leq 11$
$x leq 1$

Answer 2

-18х>13-17x
-x>13
x<-13
наиб целое -12

10х-5+6х-9х-3+4х<=3
11x-8<=3
11x<=11
x<=1
наиб целое 1

-20х4-138х3+14х2|x+7
-20x4-140x3           20x3+2x2
              2x3+14x2
              2x3+14x2
                       0
-20x4-138x3-14x2=(x+7)(20x3+2x2)
