Réponse:
factorisons chacune des expressions suivantes :
f(x) =
[tex]f(x) = 3(x - 2)( { x}^{2} + 1) - (6 {x}^{2} - 5)(x - 2) \\ f(x) = (x - 2)(3( {x}^{2} + 1) - ( {6}^{2} - 5) \\ (x - 2)(3 {x }^{2} + 3 - {6x}^{2} + 5) \\ (x - 2)( - {3x}^{2} + 8)[/tex]
[tex]f(x) = {16x}^{4} - 9 \\ f(x) = ( { {4x}^{2}) }^{2} - {3}^{2} = \\ f(x) = (4 {x}^{2} - 3)( {4x}^{2} + 3)[/tex]
[tex]f(x) = {x}^{2} - 2x + 1 - 7(x - 1) + ( x + 2)(1 - x) \\ f(x) = ( {x - 1)}^{2} - 7(x - 1) - (x + 2)(x - 1) \\ f(x)( x - 1)(x - 1 - 7 - x - 2) \\ f(x) = (x - 1)( - 10)[/tex]
f(x) = (6x-3)2 -( 2x-1)
[tex]f(x) = (6x - 3)2 - (2x - 1) \\ f(x) = 2(3)(2x - 1) - (2x - 1) \\ f(x) = (2x - 1)(6 - 1)f(x) = (2x - 1)(5)[/tex]
