The area of a rectanglular television screen is 1837 in^2. the width of the screen is 22.4 inches longer than the height. therefore, the quadratic equation that can be used to represent the area of the television screan is h(h+22.4)=1837. if you multiply, you then have the equivalent equation, h^2+22.4h=1837. complete the square to find the dimensions of the screen.
