(x^2-49)/(x^2)* (x^2-7x)/(x^2+3x-70)

Factor where possible

[ (x + 7) ( x - 7) ] / x^2 * [ x (x - 7) ] / [ ( x -7) ( x+ 10)] simplify

[ ( x + 7) ( x - 7) ] * [x / x^2 ] * 1 / [ x+ 10)] =

[ ( x + 7) ( x - 7)] * [1/x] * 1 / (x + 10)

[ ( x + 7) (x - 7) ] / [ x (x + 10) ]

[x cannot = 0 , 7, or 10]
