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 ...
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 ...
To solve a quadratic equation, we can use the ___ formula. A. linear B. quadratic C. cubic D. exponential 相关知识点: 试题来源: 解析 B。解二次方程可以用二次公式,quadratic 是二次的;linear 是线性的;cubic 是三次的;exponential 是指数的。反馈 收藏 ...
'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...
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...

An equation can be any two random mathematical expressions set equal to each other, such as "5x+2y-3b+sin(2)=e^x+3".A formula is a type of equation, but usually one that relates common quantities in a standard way that can be applied to solve other problems, such as the quadratic ...
Since the formula for the area of a rectangle is Area=length×width, then the area of this rectangle must beA=x(x+2)A=x2+x That's a quadratic equation! So, they are called quadratics because they can model the area of quadrilaterals. This is also why the naming convention of ...
