I've a question regarding completing the squares.Now how can I complete this expression below using the x2+2ax+a2+b formulae. regards,Abdullah
I take it the expression is x^2 + 2ax + a^2 + b The simple way into completing the squares is to halve the "x" coefficient (call it d) and then the square term is of the form (x + d)^2 + e and e is to balance the constant part up. https://www.mathsisfun.com/algebra/completing-square.html is a pretty good description.
