We know that for an equation ax2+bx+c=0, the sum of the roots is −ba. This means that the sum of the roots for ax2−2ax+b=0 is 2aa, or 2. The average is the sum of the two roots divided by two, so the average is 22=1.反馈...
Quadratic Equation in Standard Form: ax2 + bx + c = 0 Quadratic Equations can be factored Quadratic Formula: x = −b ±√(b2 − 4ac) 2a When the Discriminant (b2−4ac) is: positive, there are 2 real solutions zero, there is one real solution negative, there are 2 complex ...

An equation has one root or solution if the x-intercept of the graph is 1. An equation with two roots has 2 x -intercepts If there is no x – intercepts, then an equation has no real solutions. Let us understand how to use a graph for solving a quadratic equation. ...
Quadratics are the polynomial equation which has highest degree of 2. Also, called quadratic equations. Learn quadratic formulas, solution to quadratic equations with the example at BYJU'S.
(Note for the enthusiastic: the -5t2 is simplified from -(½)at2 with a=9.8 m/s2) Add them up and the height h at any time t is:h = 3 + 14t − 5t2And the ball will hit the ground when the height is zero:3 + 14t − 5t2 = 0Which is a Quadratic Equation !In...
