Bonjour Je voudrais la forme factorisee de f(x)= [tex]100- x^{2} [/tex] f(x) = [tex]4 x^{2} -116x -1560[/tex] f(x) = [tex]3 x^{2} +3x[/tex] Voila Merci

Bonjour Jolefeno

[tex]1)\-f(x)=100- x^{2} \\f(x)=10^2- x^{2}\\\\\boxed{f(x)=(10+x)(10-x)}\\\\2)\ f(x)=4x^{2} -116x -1560\\f(x)=4(x^{2} -29x -390)\\f(x)=4(x^{2} -39x+10x -390)\\f(x)=4[(x^{2} -39x)+(10x -390)]\\f(x)=4[x(x -39)+10(x -39)]\\f(x)=4[(x -39)(x+10)]\\\\\boxed{f(x)=4(x -39)(x+10)}[/tex]

[tex]3)\ f(x)=3 x^{2} +3x\\\\\boxed{f(x)=3x(x+1)}[/tex]
