X²+25=0 The question is...

Find all solutions of the equations in the complex number system.

And since I can see the answers, they are shown in the picture #9 and I don't understand how they get that. I know how they get plus or minus 5 but those 3 other answers, I'm not sure.

(I've checked on photomath and others and don't get me those 3 other answers)

answer: a

step-by-step explanation:

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.

i’m sorry but i don’t know sorry
