'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...
x = \frac {-b \pm \sqrt{b^2 - 4ac}}{2a} is a formula for finding the roots of the quadratic equation ax2 + bx + c = 0 . (chemistry) A symbolic expression of the structure of a compound. H2O is the formula for water (Dihydrogen monoxide) a plan or method for dealing ...
Roots of Polynomials Solving a polynomial requires finding the values of x. All solutions of x in a polynomial are called the roots of the polynomial. The first step is to set the equation equal to 0, eliminating the variable y. Graphically, the solutions to all polynomials are the x-...
A universal formula is derived for roots of a third-degree general algebraic equation ax 3 +bx 2 +cx+d=0 with either complex or real coefficients. This formula has the same trigonometric form both for complex and real roots. The explicit expressions for parameters of this formula for the ...
