First, combine like terms: $-7x^5 + 5x^5 + 5x^4 + 4x^4 = -2x^5 + 9x^4$, which is already in descending order.

Collect Like Terms and Then Arrange in Descending Order 5x4−7x5+4x4+5x55 x^{4}-7 x^{5}+4 x^{4}+5 x^{5}5x4−7x5+4x4+5x5

Collect Like Terms and Then Arrange in Descending Order $5 x^{4}-7 x^{5}+4 x^{4}+5 x^{5}$
