Given three integers a, b and c, print the real roots of the quadratic equation ax^2+bx+c=0. 编写程序,从键盘输入一个二元一次方程ax^2+bx+c=0的三个参数a、b、c,求此方程的实根。如果方程有实根,则输出实根,如果没有实根则输出没有实根的信息。 要求:1、三个参数a、b、c使用一条input语句输...
A。解析:一元二次方程求根公式x = [-b±√(b² - 4ac)]/2a,英语表达为x等于负b加或减b的平方减去4乘以a乘以c的平方根,再除以2乘以a。选项B中“minus or plus”顺序错误。选项C中“plus b”不符合公式。选项D中“plus b”且“minus or plus”顺序错误,所以选A。反馈...
athe standard quadratic equation, where we can now allow the coefficients b and c to be negative. Also, generalize this further to the most general form of the quadratic equation: ax2+ bx + c = 0. 标准二次方程,我们可以现在允许系数b和c是消极的地方。 并且,进一步推断这对二次方程的最一般...

Answer to: Write the equation 3x^2 = 4x + 8 in the form ax^2 + bx + c = 0. Then identify the values of a, b, and c. Do not solve the equation. By...
If the quadratic equation ax^2+bx+c=0 has -2 as one of its roots, then ax+by+c=0 represents
You can use the Quadratic Formula any time you're trying to solve a quadratic equation — as long as that equation is in the form "(a quadratic expression) that is set equal to zero". Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the ...
