Solve the radical equation. Which solution is extraneous? The solution x=-1 is an extraneous solution. Both x=-1 are x=-7 true solutions. The solution x=-7 is an extraneous solution. Neither x=-1 nor x=-7 is a true solution to the equation.

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

Step-by-step explanation:

Given

Required

Solve

Take square of both sides

Open bracket

Express as:

Expand

Factorize

Factor out x + 7

Solve:

So:

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
