Explications étape par étape

(2t-1)(t-7)-t+7

(2t-1)(t-7)-(t-7)

(t-7)[( 2t-1)-1)

(t-7)(2t-1-1)

(t-7)(2t-2)

(6x-5)²+12x-10

(6x-5)²+2(6x-5)

(6x-5)[(6x-5)+2)]

(6x-5)(6x+5-2)

(6x-5)(6x+3)

(3z-5)³-2z(3z-5)²

(3z-5)² [(3z-5)-2z))

(3z-5)²(3z-2z-5)

(3z-5)²(z-5)

(4x+3)(x-1)+2x²-2

(4x+3)(x-1)+2(x²-1)

(4x+3)(x-1)+2(x+1)(x-1)

(x-1)[(4x+3)+2(x+1)]

(x-1)(4x+3+2x+2)

(x-1)(6x+5)
