How to solve a quadratic in a non quadratic form
How to Solve a quadratic equation in a non quadratic form such as :
s² + 2abs + b² s = 4
a = 5
b = 2
Do I solve the solution by completing the square?
My tutor has advised me to substitute some values into the equation which I have done shown above, with these values it = 100
He said also to re arrange and maybe move the b² to the right hand side s² + 2abs = -b²
Do you know why he has advised me to do this?
As you can see im kinda hitting a brick wall with this quadratic so any help would be much appreciated :O)
