How to answer this on descending powers of x please help pretty please

zheka24 [161]

Answer: 25x² - 64

<u>Step-by-step explanation:</u>

(5x + 8)(5x - 8)

= 5x(5x - 8) + 8(5x - 8)

= 25x² - 40x + 40x - 64

= 25x² + 0x - 64

= $\large\boxed{25x^2-64}$

NOTE: descending powers means the biggest exponent goes first, then the next biggest exponent, etc.

For example: x⁴ then x³ then x² then x then the number (which is actually x⁰)
