If a polynomial function f(x) has roots 6 and square root of 5, what must also be a root of f(x)?
a. -6
b. square root of -5
c. 6 - square root of 5
d. 6 + square root of 5

-

Step-by-step explanation:

A root with square root or under root is only obtained when we take the square root of both sides. Remember that when we take a square root, there are two possible answers:

For example, for the equation:

If we take the square root of both sides, the answers will be:

Only getting one solution with square root is not possible. Solutions with square root always occur in pairs.

For given case, the roots are 6 and . Therefore, the 3rd root of the polynomial function f(x) had to be -

It seems you made error while writing option B, it should be - square root of 5.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w
