Question

cuadrado de un binomio ejercicios , si alguien me puede ayudar

Answer 1

$(a+b)^2= \\ (a)^2+2(a)(b)+(b)^2= \\ a^2+2ab+b^2 \\ \\ (12d-5)^2= \\ (12d)^2+2(12d)(-5)+(-5)^2= \\ 144d^2-120d+25 \\ \\ (-9r^3+y^2)^2= \\ (-9r^3)^2+2(-9r^3)(y^2)+(y^2)^2= \\ 81r^6-18r^3y^2+y^4 \\ \\ (-17d^5-13 x^{11} )^2= \\ (-17d^5)^2+2(-17d^5)(-13x^{11})+(-13x^{11})^2= \\ 289d^{10}+442d^5x^{11}+169x^{22}$
