Question

factorizar x²-10x+25     36-12m²+m⁴       25n²+90mn+81m²     9x²+12xy+4y²   1+20n+100n²        
4-16x²+64x²   por favor lo necesito para ahora 

Answer 1

2.(-3)-13≈
2x:+3+13≈
  1x-13≈
  12x

Answer 2

$x^2-10x+25=(x-5)^2$

$m^4-12m^2+36=(m^2-6)^2$

$25n^2+90mn+81m^2=(5n+9m)^2$

$9x^2+12xy+4y^2= (3x+2y)^2$

$1+20n+100n^2=(1+10n)^2$

$4-16^x^2+48x^2=4+48x^2 = 4(1+12x^2)$
