The formula for the quadratic equation is ax²+bx + c = 0, and its solution formula is x = [-b±√(b² - 4ac)]/2a. If a = 1, b = 3, c = 2, how to write this solution formula in English? A. x equals minus b plus or minus the square root of (b squared minus ...
例如:The formula for calculating the area of a circle is A = πr².(计算圆面积的公式为A = πr²。)"Equation"则更侧重于用符号表示等式左右两边相等的数学语句。它可以是一元或多元方程,也可以是微积分方程等。例如:The quadratic equation ax² + bx + c = 0 has two solutions.(二次方程...
x = \frac {-b \pm \sqrt{b^2 - 4ac}}{2a} is a formula for finding the roots of the quadratic equation ax2 + bx + c = 0. Formulation The style of expressing yourself; He suggested a better formulation His manner of expression showed how much he cared Formula (chemistry) A symboli...
For a equation ax^2 + bx + c = 0 we call a b c are coefficients of this equation where a is the coefficient of x^2 b is the coefficient of x c is the constant. Since 2x^2 - x = 3 can rewrite as : 2x^2 - 1x - 3 = 0 So the coefficients of this equation ...
'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...
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).
