Bonjour,Pourriez vous m'aider pour mes exercices svp Mercii :) Consigne factoriser l'écriture f(x) a)f(x)= x(x - 2) - (x + 3 )(2 - x) b)f(x)=x² - 4 + 4(2x + 1)

Bonjour,

f(x) = x(x - 2) - (x + 3)(2 - x)
f(x) = x(x - 2) + (x + 3)(x - 2)
f(x) = (x - 2)(x + x + 3)
f(x) = (x - 2)(2x + 3)

f(x) = x^2 - 4 + 4(2x + 1)(x - 2)
f(x) = x^2 - 2^2 + 4(2x + 1)(x - 2)
f(x) = (x - 2)(x + 2) + 4(2x + 1)(x - 2)
f(x) = (x - 2)(x + 2 + 4(2x + 1))
f(x) = (x - 2)(x + 2 + 8x + 4)
f(x) = (x - 2)(9x + 6)
f(x) = 3(x - 2)(3x + 2)

f(x) = x^2 + 4x + 4 - (x + 2)
f(x) = x^2 + 2 * x * 2 + 2^2 - (x + 2)
f(x) = (x + 2)^2 - (x + 2)
f(x) = (x + 2)(x + 2 - 1) je te laisse finir...

f(x) = (x + 1)(x + 3) - x - 1
f(x) = (x + 1)(x + 3) - (x + 1)
f(x) = (x + 1)(.... je te laisse finir

f(x)= (x - 3)² - 25
f(x) = (x - 3)^2 - 5^2
f(x) = (x - 3 - 5)(x - 3 + 5) je te laisse finir

f(x)=4 (x - 2)² - 9
f(x) = 2^2(x - 2)^2 - 3^2
f(x) = [2(x - 2) - 3][2(x - 2) + 3] je te laisse finir

f(x)= (x + 1)² - 2
f(x) = (x + 1)^2 - (V2)^2
f(x) = (x + 1 - V2)(x + 1 + V2)

f(x)= 5 - (2x - 3)²
f(x) = (V5)^2 - (2x - 3)^2
f(x) = a^2 - b^2
f(x) = (a - b)(a + b)
Je te laisse finir
