Answer:
It seems you want to find the value of the expression (4x - 1)°(2x + 5)°. However, the symbol "°" typically represents degrees in the context of angles, not multiplication. If you intend to multiply these two expressions, it would be:
(4x - 1) * (2x + 5)
To find the product, you can use the distributive property:
= 4x * 2x + 4x * 5 - 1 * 2x - 1 * 5
= 8x^2 + 20x - 2x - 5
Now, combine like terms:
= 8x^2 + 18x - 5
So, the product of (4x - 1) and (2x + 5) is 8x^2 + 18x - 5.
