Find all real and non-real roots of the function ƒ(x) = x2 + 49. Question 1 options: A) x = –7, 7 B) x = –7i, 7i C) x = –49i, 49i D) x = i + 7, i – 7

Given:

The function is:

To find:

The all the real and non-real roots of the given function.

Solution:

We have,

For roots, ,

Taking square root on both sides, we get

The roots of the given function are -7i and 7i.

Therefore, the correct option is B.

i think it is c, not positive though

step-by-step explanation:

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
