Order the steps to solve the equation
Log(x^2-15)=log(2x) form 1 to 5.
2 answers:
Answer:
- x2 − 15 = 2x
- x2 − 2x − 15 = 0
- (x − 5)(x + 3) = 0
- x − 5 = 0 or x + 3 = 0
- Potential solutions are −3 and 5
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
