Question 137450
i need to know the least common multiple of the pair of polynomials and have them factored. i am stuck on these two:
:
Factor is much as you can:
1)
{{{1/((6x^2-11x+3))}}} + {{{1/((8x^2-18))}}} = {{{1/((2x-3)(3x-1))}}} + {{{1/(2(4x^2-9))}}} = {{{1/((2x-3)(3x-1))}}} + {{{1/(2(2x-3)(2x+3))}}}
:
the common denominator will be: 2(2x-3)(3x-1)(2x+3)
:
{{{(2(2x+3)+(3x-1))/(2(2x-3)(3x-1)(2x+3))}}} = {{{(4x + 6 + 3x - 1)/(2(2x-3)(3x-1)(2x+3))}}} = {{{(7x + 5)/(2(2x-3)(3x-1)(2x+3))}}}
:
: 
2)
{{{(4r)/((r-2))}}} +  {{{(4r)/((r+2))}}} = {{{((4r)(r+2) + (4r)(r-2))/((r+2)(r-2))}}} = {{{(4r^2 + 8r + 4r^2 - 8r)/((r+2)(r-2))}}} = {{{(8r^2)/((r+2)(r-2))}}} or {{{(8r^2)/(r^2 - 4)}}}
:
Did this help?
