Question
a. factoriser chaque expression.
A= 5x + 2x +10x
B= 27x² - 27x + 27
C= 9x(x - 3) + 9x(10 + 2x)
D= (2x + 1)(8 + x) - (3x - 1)(2x + 1)
A= 5x + 2x +10x
B= 27x² - 27x + 27
C= 9x(x - 3) + 9x(10 + 2x)
D= (2x + 1)(8 + x) - (3x - 1)(2x + 1)

1. Réponse visoli
A=17x
B=27(x²-x+1)
C=9x(x-3+10+2x)=9x(3x+7)
D=(2x+1)(8+x-3x+1)=(2x+1)(-2x+9)
