Question 869188
Look for the common terms in both
1. 21abs-35ab
7ab(3s - 5)
:
2. 8a^2cd^2 - 4acd^2
4acd^2(2a - 1)
:
3. 6t^2 + 17t+12
This is a quadratic that will factor to:
(3x+4)(2x+3)
:
4. h^2 - 7h + 10
(h - 2)(h - 5)
:
5. 16x^2 - 9y^2
This the difference of squares, factors to
(4x - 3y)(4x + 3y)
:
6. 9c^2 - 24cd + 16d^2
This a perfect square
(3c - 4d)(3c - 4d)
:
7. 6t^2 - 44tb^2 + 14b 
2(3t^2 - 22tb^2 + 7b) about all you can do with this
However if you meant this to be
6t^2 - 44tb + 14b^2
factors to
(t - 7b)(6t - 2b)
