You can put this solution on YOUR website! 33. 5a to the second power b to the second power c-15abc to the second power.
---
5a^2*b^2*c - 15abc^2
---
Common Factor: 5abc
---
Factor Form:
= 5abc[ab - 3c]
====================================
34. x to the second power -7x+6. .
---
x^2-7x+6
= (x-6)(x-1)
---================================
35. 2r to the second power -3r-20
2r^2 - 3r - 20
---
= 2r^2-8r+5r-20
---
= 2r(r-4)+5(r-4)
---
= (r-4)(2r+5)
