2*2 - 12x +16 =0 4 - 12x +16 =0 -12x + 16 +4 =0 -12x + 20 =0 -12x = -20 x = 1.666666667
Presumably this is a quadratic equation question in the form of: 9x2-12x+4 = 0 When factored: (3x-2)(3x-2) = 0 Solution: x = 2/3 and also x = 2/3 (they both have equal roots)

2 to the power 0 or 20 is equal to 1
anything to the zero power equal 0
0
If you mean: 3x^2+12x+12 = 0 then it has two equal solutions of -2

To differentiate something you multiply the power on the x with the number in front of it and then reduce the power by one in this case: 12x is the same as 12x^1 so the derivitive is 12*1*x^0 which is just 12

y=12x+0 the slope is 12
If this is algebra then; 3x plus 12x = 15x
