Question

What is the product?
(2x-1)(x+4)
O2x²-4
O 2x²+4
O 2x²+7x-4
O 2x²-7x-4

Answer 1

To find the product, we can use the FOIL method, which stands for First, Outer, Inner, Last.

(2x - 1)(x + 4) = 2x • x + 2x • 4 - 1 • x - 1 • 4

Now we can simplify this:

(2x - 1)(x + 4) = 2x^2 + 8x - x - 4

Finally, we combine like terms:

(2x - 1)(x + 4) = 2x^2 + 7x - 4

Therefore, the product of (2x - 1)(x + 4) is option C.
