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
It seems like there might be a typo or missing operators in your expression "y 12x 3y9." If you intended to combine terms, it could be clearer with operators (like addition or multiplication). For example, if you meant (12x + 3y^9), it's a polynomial expression where (12x) and (3y^9) are separate terms. Please clarify if you meant something else!
12x-17x = -5
12x - 2x = 10
To simplify the expression -12x - 17 - 89, combine the constant terms -17 and -89. This results in -12x - 106. Thus, the simplified expression is -12x - 106.
(75y - 12x^2) * y = 75y^2 -12x^2y 75y - (12x^2 * y) = 75y -12x^2y
It could be either of them.
If you mean: (12x-3)(12x+3) then it is 144x^2 -9
GCF = 12x.24x = 2(12x)36x3 = 3x2(12x)
2*2 - 12x +16 =0 4 - 12x +16 =0 -12x + 16 +4 =0 -12x + 20 =0 -12x = -20 x = 1.666666667
5/4x+7/12x is the same as 15/12x+7/12x = 21/12x
12x-17x = -5
12x - 2x = 10
12x+x = 13x
12x * 4x2 = 48x3
The equation is equivalent to: -3x2 - 12x - 1 = 0 [you could change signs to get 3x2 + 12x + 1 = 0 but that is not required] The discriminant is (-12)2 - 4*(-3)(-1) = 144 - 12 = 132
12x-4y+9z+2y =12x-2y+9z
3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x
