Factoring Question help.

1. Complete the factoring.

5y + 30 = 5( )

2. Factor the trinomial

r^2 - r - 20

3. Factor completely.

-7x^6 - 14x^5 + 56x^4

4. Factor.

4r^2 - 9g^2

5. Factor.

b^2 - 14b + 49

5. Solve.

t^2 = - 24 - 11t

6. Solve the equation

2y ( y + 4) = 42

1. 5(y + 6)
2. (r - 5)(r + 4)
3. -7x^4(x^2 + 2x - 8) = -7x^4(x + 4)(x - 2)
4. (2r - 3g)(2r + 3g)
5. (b - 7)^2
5. t^2 + 11t + 24 = 0
....(t + 3)(t + 8) = 0
....t = -3, -8
6. 2y^2 + 8y - 42 = 0
....2(y^2 + 4y - 21) = 0
....(y - 3)(y + 7) = 0
....y = 3, -7
