Question

eleva al cuadrado estos binomios ​

Answer 1

Respuesta:

(a+b)²=a²+2ab+b²

(a-b)²=a²-2ab+b²

Explicación paso a paso:

a) (x+1)²=x²+2(x)(1)+1²

= x²+2x+1

d)(x-2)²= x²-2(x)(2)+2²

= x²-4x+4

g) (x+4)²=x²+2(x)(4)+4²

= x²+8x+16

j) (x-5)²= x²-2(x)(5)+5²

= x²-10x+25

(x-1/2)²= x²-2(x)(1/2)+1/2²

=x²-x+1/4

n) (x+1/2)²=x²+2(x)(1/2)+1/2²

= x²+x+1/4
