This is the concept of quadratic equations, to find out whether the two expressions we need to expand each of them:
(x)=(25+10x)(300-36x)
(x)=25(300-36x)+10x(300-36x)
(x)=7500-900x+3000x-360x^2
(x)=7500+2100x-360x^2
Expanding equation 2?
(x)=(100+20x)(100-12x)
(x)=100(100-12x)+20x(100-12x)
(x)=10000-1200x+2000x-240x^2
(x)=10000+800x-240x^2
considering the lead coeffienct
7500+2100x-360x^2≠10000+800x-240x^2
