I need help with this problem

the solutions are 5 and -5

Step-by-step explanation:

first leave it as

so working on

add like terms

get common factor (in this case 5)

divide by 5

simplify again

since 1*x = x we have

now use the difference of squares formula  

*note that 25 = 5^2

now we have two cases

and

solve for each one

and the other one is

so the solutions are 5 and -5

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

answer: what statements

step-by-step explanation if you write the statements down then i could you.
