h%28x%29=+x%5E2%2B4x%2B5

h%28h%28x%29%29=+%28h%28x%29%29%5E2%2B4%2A%28h%28x%29%29%2B5

h%28h%28x%29%29=+%28x%5E2%2B4x%2B5%29%5E2%2B4%2A%28x%5E2%2B4x%2B5%29%2B5

h%28h%28x%29%29=+%28x%5E2%2B4x%2B5%29%28x%5E2%2B4x%2B5%29%2B4%2A%28x%5E2%2B4x%2B5%29%2B5





h%28h%28x%29%29=+x%5E4%2B8x%5E3%2B30x%5E2%2B56x%2B50

Final Answer:
h%28h%28x%29%29=+x%5E4%2B8x%5E3%2B30x%5E2%2B56x%2B50
