Question

PF ajuda aí man to com dificuldade ​

Answer 1

a)

$(X+6)^{2} \\ =a^{2} + 2ab + b^{2} \\ = x^{2} + 2.x.6 + 6^{2} \\ x^{2} +12x+36$

b)

$(x+10)^{2}\\  =a^{2} +2ab + b^{2}\\   x^{2} + 2.x.10 + 10^{2}\\  x^{2} +20x+100$

c)

$(m+n)^{2} \\ =a^{2}+2ab+b^{2}\\   m^{2}+ 2.m.n +n^{2} \\  m^{2}+ 2mn+n^{2}$
