Question

Which of the following is not performed when solving r^2+12r-6=0 by

Answer 1

Answer:

B.)  why Factor p+ 12r - 6,  I did not do that below.

Step-by-step explanation:

r^2+12r-6=0

solve:

r^2  +  12 r  +   36  - 36  - 6  = 0

factor the trinomial by completing the square.

( r + 6)^2  -42 = 0

(r + 6)^2  = 42

r + 6  =  root(42 )  or  r + 6 = - root(42)

r = -6 + root(42)  or  r = -6 -root(42)

Answer 2

Answer is. ) B) factor p +12r - 6
