Explicație pas cu pas:
[tex]\bf 36(x-2)^2-25(x+1)^2 =[/tex]
[tex]\bf 6^2\cdot(x-2)^2-5^2\cdot(x+1)^2 =[/tex]
[tex]\bf [6\cdot(x-2)]^2-[5\cdot(x+1)]^2 =[/tex]
[tex]\bf [6(x-2)-5(x+1)]\cdot[6(x-2)+5(x+1)]=[/tex]
[tex]\bf (6x-12-5x-5)\cdot(6x-12+5x+5)=[/tex]
[tex]\red{\underline{\bf (6-17)\cdot(11x-7)}}[/tex]
