Question

ombine like terms z°2+z+4z°3+4z°2=4z°74z°3+5z°2+z5z°4+4z°3+z5z°3+4z°4+z

Answer 1

The given expression is

$z^2+z+4z^3+4z^2$

Remember that like terms are those which have the same variable with the same exponent.

The first and last term are like terms

$4z^3+5z^2+z$

Hence, the right answer is Option 2.
