Completing the square is a method that is used for converting a quadratic expression of the form ax2 + bx + c to the vertex form a(x - h)2 + k. The most common application of completing the square is in solving a quadratic equation. This can be done by rearranging the expression ob...
Kids Definition quadratic formula noun : a formula that gives the solutions of the general quadratic equation ax2 + bx + c = 0 and that is usually written in the form x equals 1/2a times (-b ± the square root of b2 - 4ac) ...
应用场景:在数学中,求根公式被用于解一元二次方程,也就是求解形式为ax^2+bx+c=0的方程。 造句例句: 中文:我们可以使用求根公式来解这个一元二次方程。 英文:We can use the quadratic formula to solve this quadratic equation. 中文:求根公式是解一元二次方程最常用的方法之一...
ax2+ bx + c = 0 where x represents a variable, and a, b, and c are constants with a ≠ 0. Quadratic Formula A quadratic equation has two solutions, called roots. These two solutions may or may not be distinct, and they may or may not be real. The roots are calculated by the ...

The quadratic formula is a formula used to find the roots of a quadratic equation: f(x)=ax^2+bx+c. The formula takes the values of a, b, and c of the equation and outputs the roots of the equation. The formula is x=(-b +- sqrt(b^2-4ac))/(2a). How do you prove the qua...
The general form of a quadratic equation f(x) with variable x is f(x)=ax2+bx+c=0, in which a≠0 and a,b,c ϵ R. Every quadratic equation has two roots which can be real or imaginary. The discriminant of a quadratic equation determines the nature of the roots. The roots can ...
A function of the form f(x) = ax2+ bx + c, where a ≠ 0 is called a quadratic function in variable x. Similar to afunction, a quadratic expression also has a domain and a range value. What Does Quadratic Mean in a Quadratic Expression?
ax2 + bx + c = 0 ax2 + bx = -c Step 2 If the coefficient of x2 is not 1, divide both sides of the equation by the coefficient of x2. The coefficient of x2 is a. Divide both sides of the equation by a. Step 3 Find the number that completes the square: Multiply the ...
