These are "composite" functions.
g(x+a) means insert (x+a) into g(x) to replace every x:
g(x+a) - g(x) = -5(x+a)^2 +4(x+a) +5x^2 - 4x
= -5(x^2 + 2ax + a^2) +4x +4a + 5x^2 - 4x
Now just Multiply and sum up the answer.

<em>x = 4</em>
- Step-by-step explanation:
<em>√x-3 + √x+5 = 4</em>
<em>(√x-3)² = (4-√x+5)²</em>
<em>x-3 = 16 - 8√x+5 + x+5 | -x</em>
<em>- 3 = 21 - 8√x+5</em>
<em>- 24 = - 8√x+5 | ×(-1)</em>
<em>24 = 8√x+5 | : 8</em>
<em>3 = √x+5</em>
<em>3² = (√x+5)²</em>
<em>9 = x + 5</em>
<em>x = 4</em>
