Question

What is the value(s) of x in the equation below? Simplify if necessary.
x² +5=30

Answer 1

x = -5 or 5

Step-by-step explanation:

1. subtract 5 from both sides

x^2 = 25

2. take the square root of both sides and remember to use positive and negative roots

x = ± 5

3. separate both solutions

x = -5 or x = 5

Answer 2

Answer: x=25

Explanation:

x²+5=30

30-5=25

x²=25

`√(x^2)=√(25)`

x=25
