(x+y)(x-y) a^-4a+4 m^n-9n x^+4x+2 x^+xy -4b^+2ab 3ax-12bx+3x
I don't understand
(a+b)(a-b)-(b+a)=(a+b)(a-b-1)
a(m+n)-6(m+n)=(m+n)(a-6)

In this paper, we construct a system of linear inequalities with one variable so that its solution set is - half ≤ X

This kind of inequality can be constructed a lot. Now I will construct one for you
5x-3≥3x-1
3x-1

Inequality of degree one variable 3-2 (x-1)

3－2﹙x－1﹚＜1
3－2x＋2＜1
5－2x＜1
﹣2x＜1－5
﹣2x＜﹣4
x＞2
