A problem of quadratic equation of one variable Inequality ax ^ 2 + ax-4

Hello, the perfect puzzle
Classification discussion:
① When a = 0 - 40, the original function is a quadratic function, opening up, there must be a number greater than 0
③ When a

The relationship between quadratic coefficients and constant terms of quadratic equation with one variable

They are independent of each other and have nothing to do with each other

The coefficients of quadratic term, coefficient of first term and constant term of quadratic equation with one variable are
5x²=6x-8
4x²-7=（x+1）（x-3）
x（x-5）=3（x-5）
process

5x & # 178; - 6x + 8 = 0, quadratic coefficient is 5, primary coefficient is - 6, constant term is 84x & # 178; - 7 = x & # 178; - 2x-3, 3x & # 178; + 2X-4 = 0, quadratic coefficient is 3, primary coefficient is 2, constant term is - 4x & # 178; - 5x = 3x-15, X & # 178; - 8x + 15 = 0, quadratic coefficient is 1, primary coefficient is -

The general form of quadratic equation 2x2-4x-3 = x2-2x is______ The coefficient of quadratic term is______ The coefficient of the first term is______ The constant term is______ ．

∵ 2x2-4x-3 = x2-2x ∵ 2x2-x2-4x + 2x-3 = 0, ∵ x2-2x-3 = 0, ∵ the general form is x2-2x-3 = 0, the coefficient of quadratic term is 1, the coefficient of primary term is - 2, and the constant term is - 3. So the answer is: x2-2x-3 = 0, 1, - 2, - 3
