Question

Can someone please help me rationalize this expression and state any restrictions?

Answer 1

\[\frac{ 12-x-x^2 }{ x^2-8x+15}\]

Answer 2

first factorize the both numerator and denominator...

Answer 3

and this fraction is already in the rationalized form... u have to rationalize a fraction when there r surds in the denominator ... so all u have to do is mention the restrictions

Answer 4

\[\frac{ 12 - x - x^{2} }{ x^{2} - 8x +15 } = \frac{ 12 -4x + 3x -x^{2} }{ x^{2} - 3x - 5x +15 }\]

Answer 5

@***[ISURU]*** What are "surds" ?

Answer 6

\[\frac{ 4( 3-x) + x( 3 - x)}{ x( x-3) -5(x -3) } \]
