: Solving simultaneous equations using algebraic methods (substitution and elimination) and graphical representations.
Completing the square transforms the equation into a perfect square plus a constant. Geometrically, consider ( x^2 ) as an ( x \times x ) square; ( 2x^2 ) means two such squares. The term ( -5x ) removes five ( 1 \times x ) rectangles. The goal is to rearrange them into a larger square minus a leftover area, which reveals the roots as solutions to ( (\textside)^2 = \textconstant ).
