Please help me understand the quadratic equation in disgease how do I distinguish that its a quadratic equation ? provide examples. Solution The Highest power on x will be 2. For example the equation\' x^2 + 6x + 7 = 0 Here the Highest power in x is 2 Therefore it is a Quadratic Equation. Let the equation given is x^9 + 3x^8 + 2x^2 + 7 = 0 As Here the greatest power of x is 8,therefore it is not a quadratic Equation Another Example is x^3 + x^2 + x + 1 = 0 Here the greatest power of x is 3 Therefore It is not a Quadratic Equation. .
