Question 1001746

Simplify

 {{{(1-y^2)/(y^2+4y+3)}}}........factor both numerator and denominator


{{{((1-y)(1+y))/(y^2+y+3y+3)}}}


{{{((1-y)(1+y))/((y^2+y)+(3y+3))}}}


{{{((1-y)(1+y))/(y(y+1)+3(y+1))}}}


{{{((1-y)(1+y))/((y+3)(y+1))}}}


{{{((1-y)cross((1+y)))/((y+3)cross((y+1)))}}}


{{{(1-y)/(y+3)}}}



and 

{{{(5x^2-125)/(2x^2-9x-5)}}} 


{{{5(x^2-25)/(2x^2+x-10x-5)}}}  


{{{5(x^2-5^2)/((2x^2+x)-(10x+5))}}} 


{{{5((x-5)(x+5))/(x(2x+1)-5(2x+1))}}}


{{{5((x-5)(x+5))/((x-5)(2x+1))}}} 


{{{5(cross((x-5))(x+5))/(cross((x-5))(2x+1))}}} 


{{{5(x+5)/(2x+1)}}}
