What is the answer?
R2 + 8 =

Because there is no sum we can’t find the variable (what R equals) so the answer can only be two things if you are factoring the equation the answer would be 2(R+4). If you are trying to simplify it would remain R2+8.

x = 3 - √13,  3 + √13.

or

-0.61, 6.61  to the nearest hundredth.

Step-by-step explanation:

x^2 - 6x - 4 = 0

(x - 3)^2 - 9 - 4 = 0

(x - 3)^2 = 13

x - 3 = +/-√13

x = 3 - √13,  3 + √13.
