Solve the radical equation. Which solution is extraneous? The solution x=-1 is an extraneous solution. Both x=-1 are x=-7 true s
FrozenT [24]

Answer:

Both x = -1 and x = -7 are true solutions.

Step-by-step explanation:

Given

x + 1 = \sqrt{-6x - 6}

Required

Solve

x + 1 = \sqrt{-6x - 6}

Take square of both sides

(x + 1)^2 = -6x - 6

Open bracket

x^2 + 2x + 1 = -6x -6

Express as:

x^2 + 2x+6x + 1 +6=0

x^2 + 8x + 7=0

Expand

x^2 + 7x +x + 7=0

Factorize

x(x + 7) + 1(x + 7) = 0

Factor out x + 7

(x + 1)(x + 7) = 0

Solve:

x + 1 =0\ or\ x + 7 = 0

So:

x = -1\ or\ x=-7
