bonjour
A = 2 ( x + 5 ) = 2 x + 10
B = 16 - 24 x
C = 4 x² + 2 x
d = 18 x² + 3 x
E = - 2 x - 2
F = 2 x + 2
----------------------------------------------------------------
A = 2 ( 2 x + 3 )
B = x ( x + 3 )
c = 7 ( 3 x - 2 )
d = 3 ( 2 a - b )
---------------------------------------------------------------------
A = 4 x - 5
A = 4 * ( -3) - 5 = - 12 - 5 = - 17
B = -2 ( y - 3 )
= - 2 ( 4.5 - 3 )
= - 2 * 0..5
= - 1
C = 2 x² + 3 x - 2
= 2 ( - 5 ) ² + 3 ( - 5) - 2
= 50 - 15 - 2
= 33
