Question

помогите!!!!!((((!!!!!!!!!

Answer 1

1.

$5x - 15 = 5(x - 3)$

2.

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

3.

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

4.

$\frac{1}{16} x {}^{6} - y {}^{4} = (0.25x {}^{3} - y {}^{2} )(0.25 {}^{3} + y {}^{2} )$

5.

$25a {}^{6} - 10a {}^{3} b + b {}^{2} = (5a {}^{3} - b) {}^{3}$

6.

$x {}^{2} - xy + \frac{1}{4} y {}^{2} = (x - \frac{1}{2} ) {}^{2}$

7.

$4m - 2n + 2m - n = 6m - 3n$

8.

$a {}^{2} - ab {}^{3} - ac {}^{3} + b {}^{3} c {}^{3} = (a - b {}^{3} ) {}^{}(a - c {}^{3} )$

Надеюсь помогла :)
