Bonjour,
Factoriser les expressions:
[tex] \text{ A } = 3x + 6 \\ \text { A } = \blue { 3 } \times x + \blue {3 } \times 2 \\ \text { A } = \blue { 3 } (x + 2)[/tex]
[tex]\text { B } = 12 + 18x \\ \text { B } = \orange { 6 } \times 2 + \orange { 6 } \times 3x \\ \text { B } = \orange { 6 } (3x + 2)[/tex]
[tex]\text { C } = {4x}^{2} - 20x \\ \text { C } = \green { 4x } \times x - \green { 4x } \times 5\\ \text { C } = \green{ 4x } (x - 5)[/tex]
Bonne journée.
