Solving equations
Qudaratic equations of the type:
[quadratic function] = [constant]

The task Quadratic equations of the type [vertex form]=[constant] focused on equations with a quadratic function expressed in the vertex form on one side and a constant function on the other side.

The present task focuses on quadratic equations of a more general form: one side of the equation is a quadratic function, not necessarily in vertex form; the other side is a constant function.

Convert these equations into equations of the type [vertex form]=[constant].



Investigate equations of the type:
[quadratic function]=[constant]


Convert each of the equations in the table below into the type [vertex form]=[constant].
  • Find the number of solutions of each equation, and their values.


  • solutions same equation, expressed as:
    [vertex form]=[constant]
    equation of the type:
    [quadratic function]=[constant]
        x²+(x+4)²=10
        x²+(x+4)²=9
        x²+(x+4)²=8
        x²+(x+4)²=7
        x(x-4)=5
        x(x-4)=4
        x(x-4)=-4
        x(x-4)=-5
