Step-by-step explanation:
:)
The solution would be undefined, since it is not possible for 10 to be equal to -15. Hope this helps! :)
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)
