Sagot :

F= ((5x)^-2xX6+6^)-(2x X 3x) -(2x X (-4))-(3 x 3X) -(3 x (-4))
F= 25x^-12x+36 -6x^ +8x -9x +12
F= 48 + 19x^ -13x

Si quelqu’un peut confirmer svp je suis pas sure !
[tex]F=(5x-6)^2-(2x-3)(3x-4)[/tex]
[tex]F=25x^2-60x+36-(6x^2-8x-9x+12)[/tex]
[tex]F=25x^2-60x+36-(6x^2-17x+12)[/tex]
[tex]F=25x^2-60x+36-6x^2+17x-12[/tex]
[tex]F=19x^2-43x+24[/tex]
