HELP! MEDAL REWARDED!!
What are the solutions to the following system of equations?
y = x^2 + 12x + 30
8x − y = 10

a) (−4, −2) and (2, 5)

b) (−2, −4) and (2, 5)

c) (−2, −4) and (5, 2)

d) No Real Solutions

Answer 1

\[y = x^2 + 12x + 30\\ 8x − y = 10\] change to \[y = x^2 + 12x + 30\\ y=8x-10\] then solve
\[x^2+12x+30=8x-10\]

Answer 2

x^2 + 40 = -4x ?
