800X(1-60%)X(1-x)=80 Let's solve this equation step by step. First, distribute the 800 to the terms inside the parentheses: 800 - 480X(1 - X) = 80 Next, distribute the 480X to the terms inside the parentheses: 800 - 480X + 480X^2 = 80 Combine like terms: 480X^2 - 480X + 720 = 0 Now, let's solve this quadratic equation. We can factor out a common factor of 240: 240(2X^2 - 2X + 3) = 0 The equation is equal to zero if either 240 or (2X^2 - 2X + 3) is equal to zero. Setting 240 equal to zero gives no solutions. Setting (2X^2 - 2X + 3) equal to zero: 2X^2 - 2X + 3 = 0 Using the quadratic formula, X = (-b +/- sqrt(b^2 - 4ac))/(2a), where a = 2, b = -2, and c = 3: X = (-(-2) +/- sqrt((-2)^2 - 4(2)(3)))/(2(2)) X = (2 +/- sqrt(4 - 24))/4 X = (2 +/- sqrt(-20))/4 Since sqrt(-20) is imaginary and the equation only asks for real solutions, there are no real solutions for this equation.对于简阳人来说，香肠腊肉不仅意味着迎接即将到来的新年，更是团圆时刻各家各户温暖而独特的味道。 11月15日消息，腾势汽车官方此前宣布腾势D9PREMIER创始版四座量产版将于11.17~11.26举行的2023广州车展亮相。
