a)

$25 - {y}^{2} = (5- y)(5 + y)$

b)

${x}^{2} - 0.36 = (x - 0.6)(x + 0.6)$

e)

${x}^{2} + 12x + 36 = (x + 6)^{2}$

f)

${9x}^{2} - 12x + 4 = (3x - 2)^{2}$

c)

${x}^{2} - 3 = (x - \sqrt{3} )(x + \sqrt{3} )$

d)

$- {16b}^{2} + 9 = (3 - 4b)(3 + 4b)$

g)

${4x}^{2} - \frac{4x}{5} + \frac{1}{25} = (2x - \frac{1}{5} )^{2}$
