f of x is equal to 8 x squared minus 2 x plus 3 g of x is equal to 12 x squared plus 4 x minus 3 What is h of x is equal to f of x minus g of x ?

Subtract g(x) from f(x): h(x) = (8x² − 2x + 3) − (12x² + 4x − 3). Distribute the minus sign and combine like terms: (8 − 12)x² + (−2 − 4)x + (3 + 3) = −4x² − 6x + 6. Therefore, choice C is correct.
