(2x-1)(x+2)

(2x-1)(x+2)

=2x(x+2)-1(x+2)
=2x^2+4x-x+2
=2x^2+3x+2

(2x-1)(x+2) =2x squere+3x-2

To expand the expression (2x-1)(x+2), you can use the distributive property.

First, multiply the first term of the first expression (2x) by each term of the second expression (x and 2). This gives you:

(2x) * (x) = 2x^2
(2x) * (2) = 4x

Next, multiply the second term of the first expression (-1) by each term of the second expression (x and 2). This gives you:

(-1) * (x) = -x
(-1) * (2) = -2

Now, combine all the resulting terms:

2x^2 + 4x - x - 2

Simplify the like terms:

2x^2 + 3x - 2

So, (2x-1)(x+2) expands to 2x^2 + 3x - 2.
