英文:Please make sure to pay attention to the discriminant when using the quadratic formula. 英文同义表达: '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 q...
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 ...
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 is a=2 for x^2 b= - 1 for x c= - 3 is the constant. To slove it We have t...
