simplify completely and find the restrictions 8x - 16 / x^2 - 13x + 22

Chirag :

Hi

Chirag :

(8x - 16)/(x^2 - 13x + 22) = 8(x - 2) / (x - 11)(x - 2) = 8/(x - 11) is the simplified form

Chirag :

Restrictions are those values of x which make the denominator 0

Chirag :

(x - 11)(x - 2) = 0 gives x = 11, 2

Chirag :

So, the restrictions are x ≠ 2, x ≠ 11

Chirag :

But since we have a x - 2 in the numerator as well, it cancels out, and therefore, our final answer would be

Chirag :

x ≠ 11

Chirag :

(Please ACCEPT. Thanks.)

Customer:

that makes sense.. values that make the denominator zero, why can't the math book just say that lol

Customer:

Thank you very very much
