how to write an equation in standard form with roots If and are the two roots of a quadratic equation then the formula to construct the quadratic equation is x 2 x 0 That is x 2 sum of roots x product of roots 0 If a quadratic equation is given in standard form we can
For a given quadratic equation ax 2 bx c 0 the values of x that satisfy the equation are known as its roots i e they are the values of the variable x which satisfies the equation The Example 1 Rewriting Equations in Standard Form Rewrite y 2x 6 in standard form This means that we want the variables x y to be on the left hand side and the constant 6 to be on the right hand side
