Solve the equation x. if a solution is extraneous, be sure to identify it in your final answer.

square root of the quantity x plus 7 end quantity minus 1 equals x

x=2 is the only solution

Step-by-step explanation:

The given expression is;

Add 1 to both sides of the equation;

Square both sides ;

This implies that;

Split the middle term

x=-3,or x=2

Check for extraneous solutions by substituting into the original equation.

When x=-3,

This is an extraneous solution.

When x=2,

. This is true

This is not an extraneous solution

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

yes
