The area of a circle uses a quadratic equation: {eq}A = pi \times r^2 {/eq}. You can also use quadratic functions to determine where an object will land based on the cannon's location. Notice the electrical wires hanging between utility poles? They also follow a quadratic equation to...
The meaning of QUADRATIC FORMULA is a formula that gives the solutions of the general quadratic equation ax2 + bx + c = 0 and that is usually written in the form x = (-b ±√(b2 — 4ac))/(2a).
Situations arise frequently in algebra when it is necessary to find the values at which a quadratic is zero. In other words, it is necessary to find the zeros or roots of a quadratic, or the solutions to the quadratic equation. Relating to the example of physics, these zeros, or roots,...
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...
So, given a quadratic equation {eq}ax^2 + bx + c = 0 {/eq}, this formula finds the values ofxthat make this statement true (if they exist). It looks complicated, but it is certainly nothing a decent calculator cannot handle, and it's easy to remember with a song (to the tune ...
