Answer 1

Respuesta:

$x {}^{2} - 6x + 9 \\ \\ x {}^{2} - 6x + 3 {}^{2} \\ \\ x {}^{2} - 2(x)(3) - 3 {}^{2} = = > (a - b) {}^{2} = a {}^{2} - 2ab + b {}^{2} \\ \\ (x - 3) { }^{2}$

d)

$x {}^{2} - 4 = = > a {}^{2} - b {}^{2} = (a - b)(a + b) \\ \\ x {}^{2} - 2 {}^{2} \\ \\ (x - 2)(x + 2)$

h)

$x {}^{2} - \frac{1}{2} x + \frac{1}{16} \\ \\ x {}^{2} - \frac{1}{2} x + ( \frac{1}{4} ) {}^{2} = = > (a - b) {}^{2} = a {}^{2} - 2ab + b {}^{2} \\ \\ x {}^{2} - 2(x)( \frac{1}{4} ) + (\frac{1}{4} ) {}^{2} \\ \\ (x - \frac{1}{4} ) {}^{2}$
