Please give step by step answer

Answer:
[tex]g( {x}^{2} ) = - 4( {x}^{2} ) + 2 \\ = - 4 {x}^{2} + 2 \\ h( {x}^{2} ) = {( {x}^{2} )}^{2} - 5 \\ = {x}^{4} - 5 \\ g( {x}^{2} ) + h( {x}^{2} ) \\ = - 4 {x}^{2} + 2 + {x}^{4} - 5 \\ = {x}^{4} - 4 {x}^{2} - 3[/tex]
Answer:
[tex]x^{4}[/tex] - 4x² - 3
Step-by-step explanation:
g(x) = - 4x + 2
g(x²) = - 4x² + 2
h(x) = x² - 5
h(x²) = (x²)² - 5 = [tex]x^{4}[/tex] - 5
Then
g(x²) + h(x²)
= - 4x² + 2 + [tex]x^{4}[/tex] - 5
= [tex]x^{4}[/tex] - 4x² - 3
