If 2+squareroot 3 is a polynomial root name another root of the polynomial and explain how you know it must be a root

Step-by-step explanation:

we are given one of root as

since, this is a root of polynomial

and this sqrt roots

we know that

sqrt roots and complex roots of any polynomial always exists in conjugate form

For example:

if we have root as

then other root must be conjugate of it

because both roots makes polynomial of real coefficient

so, other root must be

b

step-by-step explanation:

the word superfluous means unnecessary

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
