Question

Please give step by step answer

Answer 1

Answer:

$g( {x}^{2} ) = - 4( {x}^{2} ) + 2 \\ = - 4 {x}^{2} + 2 \\ h( {x}^{2} ) = {( {x}^{2} )}^{2} - 5 \\ = {x}^{4} - 5 \\ g( {x}^{2} ) + h( {x}^{2} ) \\ = - 4 {x}^{2} + 2 + {x}^{4} - 5 \\ = {x}^{4} - 4 {x}^{2} - 3$

Answer 2

Answer:

$x^{4}$ - 4x² - 3

Step-by-step explanation:

g(x) = - 4x + 2

g(x²) = - 4x² + 2

h(x) = x² - 5

h(x²) = (x²)² - 5 = $x^{4}$ - 5

Then

g(x²) + h(x²)

= - 4x² + 2 + $x^{4}$ - 5

= $x^{4}$ - 4x² - 3
