[(x-3) ^ (- 2)] + [2 (3x-6) ^ (- 2)] is meaningful. Find the value range of X

x≠2

The value range of X that makes 3x-1 meaningful is ()
A. x＞13B. x＞-13C. x≥13D. x≥-13

According to the meaning of the question: 3x-1 ≥ 0, the solution is x ≥ 13

Given that x ^ 2 + 3x + 5 = 9, the formula 3x ^ 2 + 9x-2 is ()

x²+3x+5=9
x²+3x=4
3(x²+3x)=3×4
3x²+9x=12
3x²+9x-2=10
