What is the quadratic form of the ff.  Please help?

1.    4x =3x^2-7

2.    2x - 8x^2 = 10

3.    8x -2 = x^2

    1) The standard form of a quadratic function is:

    ax² + bx + c = 0....where a ≠ 0

    so, 3x² - 4x - 7 = 0

    or, (3x - 7)(x + 1) = 0...in factored form

    Note, in factored form you can deduce the horizontal intercepts

    i.e. x = 7/3 and x = -1

    Standard quadratic form is:

    ax² + bx + c = 0

    So have everything on the left side and 0 on the right, then put exponents in order.

    4x = 3x² - 7

    We can subtract 4x from both sides:

    0 = 3x² - 4x - 7

    Then switch the sides:

    3x² - 4x - 7 = 0

    You can do the others.
