Answer 1

Respuesta:

Facilito

Explicación paso a paso:

1.-(a + b + c)2 = a2 + b2 + c2 + 2 · a · b + + 2 · a · c + 2 · b · c

(x2 − x + 1)2 =

= (x2)2 + (-x)2 + 12 +2 · x2 · (-x) + 2 x2 · 1 + 2 · (-x) · 1=

= x4 + x2 + 1 - 2x3 + 2x2 - 2x =

= x4- 2x3 + 3x2 - 2x + 1

2.-x2 − 2x + 1 =

= (x − 1)2

3.-x2 − 6x + 9 =

= (x − 3)2

4.-x2 − 20x + 100 =

= (x − 10)2

5.- x2 + 10x + 25 =

= (x + 5)2

Espero te ayude :)
