Best ResponseYou've already chosen the best response.1\[\frac{ 4y }{ y^281 }\times \frac{ y+9 }{ 2y^2 }\] use the identity a^2  b^2=(a+b)(ab) in here  y^2 81 u et\[\frac{ 4y }{ (y+9)(y9) }\times \frac{ y+9 }{2y^2}\]cut out the common things from numerator and denominator u get\[\frac{ 2 }{ y(y9) }\]

Best ResponseYou've already chosen the best response.0Oh okay i understand. There a harder one that i have no idea about, find the lcd for x^2/(x^2+4x+3) and 2x/ (x^2+x6)

Best ResponseYou've already chosen the best response.1x^2+4x+3 >(x+3)(x+1) x^2+x6>(x+3)(x2) so the lcd wuld be (x+3)(x2)(x+1)

Best ResponseYou've already chosen the best response.1\[\frac{ x^26x }{ 7}\div \frac{ (x6) }{ x}\] we know that \[a \div b =a \times \frac{ 1 }{ b }\] so we get  \[\frac{ x^26x }{ 7 } \times \frac{ x }{ (x6) }\] take x common from x^26x u get>x(x6) \[\frac{ x(x6) }{ 7 } \times \frac{ x }{ x6 }\]\[\frac{ x^2 }{ 7 }\]
