Question

JULGUE (V) OU (F). CORRIJA OS FALSOS:

( ) 1 - 6 M + 9 = __________________
( ) p6 - 10p³ q²+ 25 q4 = ( p³ - 5 q²) = __________________
( ) h ² - 5 h + 25 = (h - 5)² = ___________________________
( ) b² + 6 + 9 = ( b + 3)² = ____________________________
( ) 9 x² + 30 xy + 25 y² = ____________________________

Answer 1

(  ) 1 - 6 M + 9 = ___10-6M = 2(5-3M)_

( V ) p6 - 10p³ q²+ 25 q4 = ( p³ - 5 q²) = __________________

( F ) h ² - 5 h + 25 = (h - 5)² = __h(h-5)+25___

( F ) b² + 6 + 9 = ( b + 3)² = ____b² + 15__

(  ) 9 x² + 30 xy + 25 y² = ____(3x+5y)²___
