(2x-3)(3x-5) Express As A Trinomial

Expanding (2x-3)(3x-5) into a Trinomial

This problem involves expanding a product of two binomials, resulting in a trinomial. Here's how to do it:

Using the FOIL method

First: Multiply the first terms of each binomial. (2x) * (3x) = 6x²

Outer: Multiply the outer terms of the binomials. (2x) * (-5) = -10x

Inner: Multiply the inner terms of the binomials. (-3) * (3x) = -9x

Last: Multiply the last terms of each binomial. (-3) * (-5) = 15

Now, add all the results together:

6x² - 10x - 9x + 15

Combine the like terms:

6x² - 19x + 15

Therefore, (2x - 3)(3x - 5) expressed as a trinomial is 6x² - 19x + 15.

Alternative Method: Distributive Property

You can also use the distributive property to achieve the same result:

  1. Distribute the first term of the first binomial: (2x) * (3x - 5) = 6x² - 10x

  2. Distribute the second term of the first binomial: (-3) * (3x - 5) = -9x + 15

  3. Combine the results: 6x² - 10x - 9x + 15 = 6x² - 19x + 15

Both methods lead to the same trinomial. Choose whichever method feels more comfortable for you.
