Question

3. One solution of x2 - 5x - 1 = 0 is​

Answer 1

Let's solve your equation step-by-step.
2x−5x−1=0

Step 1: Simplify both sides of the equation.
2x−5x−1=0
2x+−5x+−1=0
(2x+−5x)+(−1)=0
(Combine Like Terms)
−3x+−1=0
−3x−1=0

Step 2: Add 1 to both sides.
−3x−1+1=0+1
−3x=1

Step 3: Divide both sides by -3.
-3x/-3=1/-3
x=−1/3

Answer:
x=−1/3
