Question
Factoriser, si possible, les trinômes suivants
.1. f(x)= x2 - 6x - 7
2. f(x) = -x2 + 2x + 8
3. f(x) = -3x2 + 5x + 2
4. f(x) = 3x2 + x +4
5. f(x)=-4x2 + 28x – 49
6. f(x)= x2 – x-1
.1. f(x)= x2 - 6x - 7
2. f(x) = -x2 + 2x + 8
3. f(x) = -3x2 + 5x + 2
4. f(x) = 3x2 + x +4
5. f(x)=-4x2 + 28x – 49
6. f(x)= x2 – x-1
