F= 25 - (3x - 2)au carré
a) Developper et reduire f
b) Factoriser f
c) calculer f pour x = 7 sur 3
Simplifier (a+1)au carré - (a-1)au carré, puis calculer 100 001au carré - 99 999au carré
Meme exercice pour (2x +1)au carré - (2x-1)au carré et 2001au carré - 1999au carré

F=25-(3x-2)²
a )F=25-9x²+12x-4=-9x²+12x+21
b) F=25-(3x-2)²=5²-(3x-2)²
F=(5+3x-2)(5-3x+2)
F=(3x+3)(7-3x)
F=3(x+1)(7-3x)
c) Si x=7/3, F=3(7/3+1)(7-7)=0
(a+1)²-(a-1)²=a²+2a+1-a²+2a-1=4a
Tu appliques pour a=100.000
(100.000+1)²-(100.00-1)²=100.001²-99.999²=4*100.000
(2x+1)²-(2x-1)²=4x²+4x+1-4x²+4x-1=8x
Tu appliques pour x=1000
(2*1000+1)²-(2*1000-1)²=2001²-1999²=8*1000
