Find the solution of 5 times the square root of the quantity of x plus 7 equals negative 10, and determine if it is an extraneous solution

we are given

5 times the square root of the quantity of x plus 7

so, we get

left side is

right side is -10

so, we can set them equal

Since, we have to solve for x

so, we will isolate x one anyone side

and then we can solve for x

we take square both sides

Divide both sides by 25

Subtract both sides by 7

Extraneous solution:

we can plug x=-3 into original

we know that 10 is not equal to -10

so, x=-3 is not valid solution

Hence, this is extraneous solution...........Answer
