me pueden ayudar a factorizar estos polinomios x^{2} + 4x+4= x^{2} +8x+15= x^{2}+3-28= x^{2}-81=6 x^{2}-4x= x^{2}-10x+25= x^{2}-5x-14= x^{2}-9x+18=4 x^{2}-36=8 x^{2}-12x=

Respuesta :

1. ( x + 2 ) (x+2 )
2. ( x +5 ) (x+3)
3. ( x + 7 ) ( x-4 )
4. (X+ 9 ) ( x- 9 )
5. 2x (3x - 2 )
6. ( x - 5 ) ( x-5)
7. ( x + 2 ) ( x -7)
8. ( x - 3 ) (x-6)
9. (2x - 6 ) ( 2x + 6 )
10. 4x ( 3x -4 )
x²+4x+4 = (x+2)(x+2)

x²+8x+15 = (x+3)(x+5)

x²+3x-28 = (x+7)(x-4)

x²-81 = (x+9)(x-9)

6x²-4x = x(6x-4)

x²-10x+25 = (x-5)(x-5)

x²-5x-14 = (x-7)(x+2)

x²-9x+18 = (x-6)(x-3)

4x²-36 = (2x-6)(2x+6)

8x²+12x = 8x(x+ 3/2)
