bonjour
f (x) = ( 2 x + 3 ) ( x - 4 )
f ( 0) = 3 * - 4 = - 12
f ( 1) = ( 2 + 3 ) * ( 1 - 4) = 5 * - 3 = - 15
g ( x) = 2 x² - 5 x - 12
g ( 0) = - 12
g ( 1 ) = 2 - 5 - 12 = - 15
donc Tom a raison
( 2 x + 3 ) ( x - 4 ) = 2 x² - 5 x - 12
2 x² - 8 x + 3 x - 12 = 2 x² - 5 x - 12
2 x² - 5 x - 12 = 2 x² - 5 x - 12
donc Emma a raison
