Question

3(x-2)^2(x+5)=3(x+1)^2(x-1)+3
Resolver

Answer 1

3(x2-4x+4)(x+5)=3(x2+2x+1)(x-1)+3
3(x3-4x2+4x+5x2-20x+20)=3(x3+2x2+x-x2-2x-1)+3
3(x3-4x2+5x2+4x-20x+20)=3(x3+2x2-x2+x-2x-1)+3
3(x3+x2-16x+20)=3(x3+x2-x-1)
3x3+3x2-48x+60=3x3+3x2-3x-3
3x3-3x3+3x2-3x2-48x+3x=-3-60
-48x+3x=-63
-45x=-63
X=-63/-45
X=63/45
