Question

desenvolva algebricamente cada quadrado da soma de dois termos​

Answer 1

Resposta:

$(x+5)^2\\\\=x^2+2x\cdot \:5+5^2\\\\=x^2+10x+25$

$(7a + 1)^1\\\\=7a+1$

$(x+2y)^2\\\\=x^2+2x\cdot \:2y+\left(2y\right)^2\\\\=x^2+4xy+4y^2$

$(x^2 +1)^2\\\\=\left(x^2\right)^2+2x^2\cdot \:1+1^2\\\\=x^4+2x^2+1$
