We know that FX = x square + (a + 1) + a square, if FX can be expressed as the sum of an odd function GX and an even function HX (1) Find the analytic expressions of GX and HX. (2) if FX and GX are decreasing functions in the interval (- ∞), (a + 1) square), find the value range of F1

Are you sure you are right? If a is a known number, the answer is not unique
Here's an example
(1)hx= (x-1)^2+a+a^2 gx=2x
(2) If you remember correctly, the decrement is less than 0 after the derivation, so you can't use the a of the original formula. The formula is wrong
