Theo started to solve the quadratic equation (x 2)2 – 9 = –5. he added 9 to both sides and the resulting equation was (x 2)2 = 4. next, he took the square root of each side. which was the resulting equation of that step? x 2 = ±4 x 2 = ±2 x 2 = ±8 x 2 = ±16

B.

Step-by-step explanation:

We are given that,

The solution of the quadratic equation by Theo is,

i.e. .............Adding 9 on both sides

i.e.

i.e.  ...............Taking square root on both sides

Hence, we see that,

The resulting equation of the step 'Taking square root on both sides' is given by,

B.

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
