Question

solve by completing the square method 5x²-6x-2=0​

Answer 1

Answer:

5x^2-6x-2=0

Or, (x√5)^2-2*(x√5)*(3/√5)+(3/√5)^2-2-(3/√5)^2

Or,(x√5-3/√5)^2 -2-(9/5)

Or,(x√5-3/√5)^2-[2+(9/5)]

Or,[x√5-(3/√5)]^2- (19/5)

Or,[x√5-(3/√5)]^2-(√19/√5)^2

Now split it into a^2-b^2=(a+b).(a-b) and get the answer
