Answer:
\(2x^2+7x-4\)
Step-by-step explanation:
The distributive says that:
\(a \cdot(b+c) = a\cdot b+ a\cdot c\)
To find the product of :
\((2x-1)(x+4)\)
then;
\(2x(x+4)-1(x+4)\)
Using distributive property we have;
\(2x^2+8x-x-4\)
Combine like terms;
\(2x^2+7x-4\)
Therefore, the product of \((2x-1)(x+4)\) is, \(2x^2+7x-4\)
