Question

Order the steps to solve the equation Log(x^2-15)=log(2x) form 1 to 5.

Answer 1

Answer:

1. x2 − 15 = 2x
2. x2 − 2x − 15 = 0
3. (x − 5)(x + 3) = 0
4. x − 5 = 0 or x + 3 = 0
5. Potential solutions are −3 and 5

Answer 2

Step 1: x²-15=2x
step 2: x²-2x-15=0
step 3: (x-5)(x+3)=0
step 4: x-5=0 or x+3=0
step 5: x=5 of x=-3
