(D)
'cause
(14x)^0 = 1

Steve these  signs are throwing me off....so even though that is  (14x)to the 0  which = 1 it is a negative still?

Math Ms.Sue 
Steve
yes. (14x)^0 = 1, so (14x)^0 = (1) = 1
now, (14x)^0 = 1, because the  sign is part of what is raised to the 0 power.
Powers are done before +/ unless parens change the order.

It's nice when it finally clicks, eh?
Maybe it will help if you consider a leading "" as preceded by a 0. So,
x^2 = 0x^2
now it is clear that the powers get done before the subtraction.
(2x)^3 = 0(2x)^3 = 0  1/(2x)^3 = 0  1/8x^3 = 1/8x^3

solve the following quadratic equation and show steps 2z^4 +14z^3 + 20z^2 
Math
you know that 8x = 5y you know that 3y=14z since 5 = (5/3)*3, 5y = (5/3)*(3y) so, 5y = (5/3)(3y) = (5/3)(14z) = (70/3)z now you have 5y, which is the same as 8x. You want 12x. since 12 = (3/2)*8, 12x = (3/2)*8x. 12x = (3/2)(8x) = (3/2)(5y) …
