Question

Estos binomios estan correctos
(x+8)² = (x)²+2(x)(8)+(8)²=64
(x-1)² = (x)²-2(x)(1)+(1)² = 1
(a+10x)² = (a)²+2(a)(10)+(10)² =100

Answer 1

(x+8)² = (x)²+2(x)(8)+(8)² = 64
Rpta: (x)²+ 16x + 64



(x-1)² = (x)²-2(x)(1)+(1)² = 1
Rpta : x²-2x+1


(a+10x)² = (a)²+2(a)(10)+(10)² =100
Rpta: a²+20ax + 100x²
