Answer 2

Solution for (2a + 1)(a - 2)

To expand the expression (2a + 1)(a - 2), we can use the distributive property to multiply each term in the first expression by each term in the second expression and then combine like terms.

Expanding (2a + 1)(a - 2) gives us: 2a * a - 2a * 2 + 1 * a - 1 * 2

Simplifying further: 2a^2 - 4a + a - 2

Combining like terms: 2a^2 - 3a - 2

So, the expanded form of (2a + 1)(a - 2) is 2a^2 - 3a - 2.
