Bonjour,
J'ai un petit doute sur mes calculs, je suis en troisième
A = -3(2x + 7)
= -3*2x + (-3)*7
= -3*2x + (-21)
= 2x + (-24)
= 2x - 24
B = -2x(3x + 4)
= -2x*3x + (-2x)*4
= -1x + 4
C = -5x(1 - 2x) - 4x // - 4x est une soustraction !!
= -5x*1 - (-5x)*2x - 4x
= 1 - 2x - 4x
= 1 - (-2x)
= 1 + 2x
Si quelqu'un peut m'aider et me confirmer ce que j'ai fait, ça serait cool :d
