Va rog ajutati-ma...
Descompuneti in factori:

3x²-x-2
2x²+7x+3
6x²+7x+2


Răspuns :

3x^2 - x - 2 = 3x^2 - 3x + 2x - 2 = 3x(x - 1) + 2(x -1) = (x- 1)(3x + 2)

2x^2 + 7x + 3 = 2x^2 + 6x + x + 3 = 2x(x + 3) + (x + 3) = (x + 3)(2x + 1)

6x^2 + 7x + 2 = 6x^2 + 4x + 3x + 2 = 2x(3x + 2) + (3x + 2) = (3x + 2)(2x + 1)
