2. 3-y-10y²
3. 6t²+13t-28
4. 12c²+14c-6
5. 6a²-7ab-10b²

Answer 1

5x^ +17x +6
5x^ +15x +2x +6
5x(x + 3) +2(x +6)

3 -y -10y^
3 -6y +5y -10y^
3 (1 -2y) 5y(1 -2y)

12c^ +14c -6
12c^ -4c +18c -6
4c(3c^ -1) 6(3c -1)

6a^ -7ab -10ab^
2 x (6a) (10ab) =120a^b

Answer 2

1. 5x" + 17x + 6
= (5x + 2) (x + 3)
2. 3 - y - 10y"
= (1 - 2y) (3 + 5y)
3. 6t" + 13t - 28
= (2t + 7) (3t - 4)
4. 12c" + 14c - 6
= (6c - 2) (2c + 3)
5. 6a" - 7ab - 10b"
= (6a + 5b) (a - 2b)
