Question

How would you solve: Z^2+2z+1 * 5/z+1?

Answer 1

Is this about complex numbers?

Answer 2

Lol no...it's multiplying rational expressions.

Answer 3

If that is the case, then multiply the fraction by a fraction that has both numerator and denominator with the opposite sign of the expression of the denominator of the first fraction.
That is:\[\frac{ z^2+2z+1*5 }{z+1}*\frac{ z-1 }{ z-1}=\frac{ (z^2+2z+5)(z-1) }{ 1^2+1^2 }\] You can carry on from here.

Answer 4

Ok. Thank you so much!

Answer 5
