Question 65383
Rational and Radical Expressions 
1)  Simplify: 
{{{(16x^2+8x+1)/(1-16x^2)}}}
{{{((4x+1)(4x+1))/(-(4x+1)(4x-1))}}}
{{{-(cross((4x+1))(4x+1))/(cross((4x+1))(4x-1))}}}
{{{-(4x+1)/(4x-1)}}}
{{{highlight((4x+1)/(1-4x))}}}
:
2) Multiply and Simplify: 
{{{((x^2-7x+12)/(x^2-6x+8))*((x^2+6x+8)/(x^2-x-6))}}}
{{{((x-4)(x-3)/((x-4)(x-2)))*((x+4)(x+2)/((x-3)(x+2)))}}}
{{{(cross((x-4))*cross((x-3))/(cross((x-4))*(x-2)))*((x+4)*cross((x+2))/(cross((x-3))*cross((x+2))))}}}
{{{highlight((x+4)/(x-2))}}}
:
3) Divide and simplify:  5x-7 ÷  25x²-49  
                                 —————————           
                                 5x²+27x+28

{{{(5x-7)*((5x^2+27x+28)/(25x^2-49))}}}
{{{(5x-7)*((x+4)(5x+7)/((5x+7)(5x-7)))}}}
{{{cross((5x-7))*((x+4)*cross((5x+7))/(cross((5x+7))*cross((5x-7))))}}}
{{{highlight(x+4)}}}
Happy Calculating!!!
