4. 3y2 + 8y + 4
5. 5x2 + 13x + 6
6. 3y2 – 8y + 4
7. 8p2 – 14p + 5
8. 12m2 - 8m + 1
9. 10a2 – 43a + 12
10. 12x2 - 34x + 10

Answer 1

1. 2x2 + 7x +3 = (2x + 1)(x + 3)
2. 3x2 + 8x +5 = (3x + 5)(x + 1)
3. 2x2 + 5x + 3 = (2x + 3)(x + 1)
4. 3y2 + 8y + 4 = (3y + 2)(y +  2)
5. 5x2 + 13x + 6 = (5x + 3)(x + 2) 
6. 3y2 – 8y + 4 = (3y - 2 )(y - 2)
7. 8p2 – 14p + 5 = (4p - 5)(2p - 1)
8. 12m2 - 8m + 1 = (6m - 1)(2m - 1)
9. 10a2 – 43a + 12 = prima
10. 12x2 - 34x + 10  = (6x - 2)(2x - 5)
