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