The meaning of QUADRATIC FORMULA is a formula that gives the solutions of the general quadratic equation ax2 + bx + c = 0 and that is usually written in the form x = (-b ±√(b2 — 4ac))/(2a).
'quadratic formula' 可以被表达为 'formula for finding roots of a quadratic equation',这强调了其用于寻找二次方程的根。 另一个同义表达是 'formula for solving quadratic equations',这同样强调了其解决二次方程的应用。 'quadratic formula' 也可以被简称为 'the formula',在上...
