Question 205641
1. {{{(6a^2-8a-8)/(2a^2-9a-56)/(a-2)/(a-8)}}}
- first start by factoring the polynomials
2. {{{((6a+4)(a-2))/((2a^2-9a-56)(a-2)(a-8))}}}
3. {{{((6a+4)(a-2))/((2a+7)(a-8)(a-2)(a-8))}}}
- Now Cross out like terms
4. {{{(6a+4)/((2a+7)(a-8)^2)}}}
- Next simplify the denominator
5. {{{(6a+4)/((2a+7)(a^2-16a+64))}}}
6. {{{(6a+4)/(2a^3-32a^2+128a+7a^2-112a+448)}}}
7. {{{(6a+4)/(2a^3-25a^2+16a+448)}}}
- Now either
{{{(6a+4)/((2a+7)(a-8)^2)}}} or {{{(6a+4)/(2a^3-25a^2+16a+448)}}}
may be correct depending on you teacher and the book you are using but they are essentially the same answer
