Answer 2

It seems like you have a polynomial expression on the left-hand side, and you want to check if it's equal to the expression on the right-hand side. Let's simplify the left-hand side and see if it indeed equals the right-hand side.

Given:

(2x - 3)(2x - 5)

To simplify this expression, you can use the distributive property (FOIL method):

(2x - 3)(2x - 5) = 2x * 2x - 2x * 5 - 3 * 2x + 3 * 5

Now, calculate each term:

4x^2 - 10x - 6x + 15

Combine like terms:

4x^2 - 16x + 15

So, the simplified form of (2x - 3)(2x - 5) is 4x^2 - 16x + 15.

Now, let's compare this result to the expression on the right-hand side:

4x^2 - 14x + 23

These two expressions are not equal:

4x^2 - 16x + 15 ≠ 4x^2 - 14x + 23

There seems to be an error in your initial equation. If you intended for them to be equal, please double-check the original equation or provide more context for clarification.

Answer 3

Let's verify if the given expression is equal to $4x^2 - 14x + 23$ by multiplying $(2x - 3)$ and $(2x - 5)$ using the distributive property.

$(2x - 3)(2x - 5)$

First, multiply the terms in the first parentheses by each term in the second parentheses:

$= 2x * 2x - 2x * 5 - 3 * 2x + 3 * 5$

Now, simplify each term:

$= 4x^2 - 10x - 6x + 15$

Combine like terms:

$= 4x^2 - 16x + 15$

So, $(2x - 3)(2x - 5)$ is equal to $4x^2 - 16x + 15$, not $4x^2 - 14x + 23$. It appears there might be a mistake in the expression you provided.
