Which equations have a leading coefficient of 3 and a constant term of -2?

0 = 3x² + 2x - 2

Perfect example of a leading coefficient (coefficient of the highest degree term) of 3 and a constant term (degree zero) of -2.  CHECK ME

0 = -2 - 3x² + 3

That has a leading coefficient of -3 and a constant of -2+3=1, so don't check me.

0 = -3x + 3x² - 2

CHECK ME.   The order we write the terms doesn't matter; the leading coefficient is on the highest degree, 3x² here.   The constant is -2.

0 = 3x² + x + 2

The leading coefficient is indeed 3 but the constant is a positive two, don't check me.

0 = -1x - 2 + 3x²

CHECK ME.  Again, the written order of the terms doesn't matter; it's the degree that matters.

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
