​

Answer 1

Respuesta:

$( \frac{1}{6} a – \frac{1}{9} b) + ( \frac{1}{21} by - \frac{1}{14} ay) = \\ \\ \frac{1}{18} (3a - 2b) - \frac{1}{42} y(3a - 2b) = \\ \\ \frac{1}{126} (3a - 2b)(7 - 3y)</p><p>$

$( {w}^{2} + {w}^{2} {y}^{2} + {w}^{3}) + (w + 1 + {y}^{2} ) = \\ \\ {w}^{2} + {w}^{2} {y}^{2} + {w}^{3} + w + 1 + {y}^{2} = \\ \\ {w}^{2} (1 + {y}^{2} + w) + w + 1 + {y}^{2} = \\ \\ (1 + {y}^{2} + w)( {w}^{2} + 1)$
