2x^2+7x-4; 2x times x =2x^2; +8x from 2x times 4; minus x from -1 times x; minus 4 from -1x4.

Answer:

[tex]2x^{2}+7x-4[/tex]

Step-by-step explanation:

We are given to find the product of (2x-1) and (x+4).

So, we have,

[tex](2x-1)(x+4)[/tex] = [tex]2x^{2}+8x-x-4[/tex] = [tex]2x^{2}+7x-4[/tex].

Thus, the product of (2x-1) and (x+4) is [tex]2x^{2}+7x-4[/tex].

i.e. [tex](2x-1)(x+4)[/tex] = [tex]2x^{2}+7x-4[/tex].
