Algebra 2 . solving equations containing two radicals

These are 3 questions and 3 answers.

Question 1.

bot equations have the same potential solutions, but equation A may have extraneous solutions

Explanation:

1) Equation A

Replace x = -4 in the right side of the equation:

Which is not defined, so this is a extraneous solution.

2) Equation B.

Since it is a cube root, it is defined for any (negative, zero, and positive) values of x.

Question 2.

cubing both sides once.

Explanation:

3) Question 3.

c - 2 = 25 + c + 10√c

Explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
