Answer 1

1) $x^{2} -4=(x-2)(x+2)$

2)$25-9a^{2} =(5-3a)(5+3a)$

3)$36m^{2} -100n^{2} =4(3m-5n)(3m+5n)$$</p><p>4)[tex]0,04p^{2} -1,69q^{2}=frac{1}{100}*(2p-13q)(2p+13q)$

5)$x^{2}y^{2}-frac{4}{9}=(xy-frac{2}{3})(xy+frac{2}{3})$

6)$a^{4}-b^{6}=(a^{2}-b^{3})(a^{2}+b^{3})$

7)$0,01c^{2}-d^{8}=(frac{1}{10}c-d^{4})(frac{1}{10}c+d^{4})$

8)0,81y^{10}-400z^{12}=(frac{9}{10}y^{5}-20z^{6})(frac{9}{10}y^{5}+20z^{6})

9)$-1+49a^{4}b^{8}=(7a^{2}b^{4}-1)(7a^{2}b^{4}+1)$

10)$1frac{7}{9}m^{2}n^{2}-1frac{11}{25}a^{6}b^{2}=frac{1}{225}*(175m^{2}n^{2}-99a^{6}b^{2})$
