Factoriser une expression à l'aide d'un facteur commun Exercice

15x + 5 = 5 \times (3x + 1)

15x + 5 = 5x \times (3x + 1)

15x + 5 = 5 \times (3 + x)

15x + 5 = 5x \times (3 + 1x)

9x^2y^2 + 3xy = 3xy \times (3xy + 1)

9x^2y^2 + 3xy = 3 \times (3xy + xy)

9x^2y^2 + 3xy = 3xy \times (3 + xy)

9x^2y^2 + 3xy = 3x^2y^2 \times (3xy + 1)

4xy + 40x^2 = 4x \times (y + 10x)

4xy + 40x^2 = 4x \times (xy + 4x)

4xy + 40x^2 = 4x \times (y + 4)

4xy + 40x^2 = 4 \times (xy + 4x)

3y^2 − 9y = 3y \times (y − 3)

3y^2 − 9y = 3y \times (y + 3)

3y^2 − 9y = 3 \times (y^2 − 3)

3y^2 − 9y = 3y \times (y − 3y)

8xy^2z − 4yz = 4yz \times (2xy − 1)

8xy^2z − 4yz = 4xyz \times (2y − 1)

8xy^2z − 4yz = 4y \times (2xy − z)

8xy^2z − 4yz = 4xyz \times (2y − 1)
