Convert the simplified parabolic equation y=3x^2-30x-7 to standard form.

3x^2-30x-7
3x^2 -30 x -7 +75 -75

3(x^2 -10x + 25) -82
3(x-5)^2 -82

or
y = 3(x-5)^2 -82

check that.

    I need to find the value of x. 9x^3 + 9x = 30x^2 It's confusing because apparently I have to do 9x^3 + 9x and then add the + 30x^2 to it, and then make it equal 0, so it ends up like this: 9x^3 + 9x + 30x^2 = 0 And afterward, I would …
