Question

-3(x+7)^2=-42. can anyone show me how to solve this problem and if so can you please show work or give me a brief description?

Answer 1

divide both sides by \(-3\) first to get rid of the \(-3\) out front
what do you get?

Answer 2

(x+7)^2=14?

Answer 3

looks good to me
then take the square root of both sides, don't forget the \(\pm\)

Answer 4

in other words, just write
\[x+7=\pm\sqrt{14}\]

Answer 5

then solve by subtracting \(7\)

Answer 6

subtract 7 from radical 14? like this 7-\[\sqrt{14}\]

Answer 7

no, subtract 7
\[-7\pm\sqrt{14}\]

Answer 8

ok, thank you(:
