To find an expression equivalent to \((x - 5)(2x + 3)\), we can use the distributive property (also known as the FOIL method for binomials).
Let's expand the expression:
\[ (x - 5)(2x + 3) = x(2x) + x(3) - 5(2x) - 5(3) \]
Calculating each part, we get:
\[ = 2x^2 + 3x - 10x - 15 \]
Now, combine like terms:
\[ = 2x^2 + (3x - 10x) - 15 \] \[ = 2x^2 - 7x - 15 \]
So, the expression equivalent to \((x - 5)(2x + 3)\) is:
\[ \boxed{2x^2 - 7x - 15} \]
