7t+7y= 7(t+y)

8a-8b+8c = 8(a-b+c)

3x+3y+3xz = 3(x+y+xz)

2t+7t = t(2+7) =9t

7ty-3y = y(7t-3)

ax+bx = x(a+b)

2x-5x+3x = x(2-5+3) = 0

9x+kx = x(9+k)

6ty-7y = y(6t-7)

Tx+7tx+2x = x(t+7t+2)= x(8t+2)

abc-dec = c(ab-de)

3t+7t

Factoriser veut dire trouver ce qui est commun au chiffre ou à la lettre de l'expression
7t+7y = 7(t + y)
8a-8b+8c = 8 (a -b +c)
3x+3y+3xz = 3 (x +y + xy)
2t+7t = t ( 2 + 7 )
7ty-3y = = y (7t -3)
ax+bx = x(a +b)
2x-5x+3x = x ( 2 -5 +3)
9x+kx = x( 9 +k)
6ty-7y = y ( 6t -7)
tx+7tx+2x = x ( t +7t +2)
abc-dec = c ( a X b - d X e)
3t+7t = t ( 3 +7)
