X²+10x+25=

4X²+4xy+Y²=

X²-20x+100=

4/9x²+40/9x+25=
​

Answer 1

Explicación paso a paso:

1.

$x1 = \frac{25 + 10 \sqrt{5} }{2} \\ x2 = \frac{25 - 10 \sqrt{5} }{2}$

2.

$(x + 5)(x + 5)$

3.

$(2x + y) ^{2}$

4.

$(x - 10)(x - 10)$

5

$x1 = - 5 + \frac{5 \sqrt{5} }{2} i \\ x2 = - 5 - \frac{5 \sqrt{ 5} }{2} i$
