Question

plz helppp solve each and write in interval notation a) x(x−1)(x+2)>0
b) /x−4/<3
c)2x−3≤1

Answer 1

B

Answer 2

a) values for equation = 0 are 0,1,-2
to satisfy inequality x: x >1

b) visualize 2 inequalities -ve value and +ve value
(x-4)>-3 and x-4<3
x-4>-3 and x -4 < 3
x >-3+4 and x < 3 + 4
x >1 and x<7

x: 1<x<7

c) 2x-3<=1
2x<=1 + 3 =4
x <=2
x: x<=2
