To write a quadratic equation in standard form, use the format ( ax^2 + bx + c = 0 ), where ( a ), ( b ), and ( c ) are constants, and ( a \neq 0 ). Start with the equation in any other form and rearrange it to have the ( x^2 ) term first, followed by the ( x ) term, and then the constant term. Ensure all terms are on one side of the equation, leaving zero on the other side. For example, if you have ( x^2 + 5x - 4 = 3 ), you would rearrange it to ( x^2 + 5x - 7 = 0 ).
