Math Problem Statement

(2x - 3)(3x - 4) is equivalent to:

Solution

To solve the expression (2x3)(3x4)(2x - 3)(3x - 4), we'll need to expand the product using the distributive property (also known as FOIL for binomials). Here's the step-by-step process:

Step 1: Use FOIL (First, Outer, Inner, Last)

  • First: Multiply the first terms in each binomial:
    2x3x=6x22x \cdot 3x = 6x^2

  • Outer: Multiply the outer terms:
    2x4=8x2x \cdot -4 = -8x

  • Inner: Multiply the inner terms:
    33x=9x-3 \cdot 3x = -9x

  • Last: Multiply the last terms in each binomial:
    34=12-3 \cdot -4 = 12

Step 2: Combine like terms

Now, add all the terms together: 6x28x9x+126x^2 - 8x - 9x + 12

Combine the xx-terms: 6x217x+126x^2 - 17x + 12

Final answer:

The expanded expression is 6x217x+126x^2 - 17x + 12.

Looking at the options, the correct choice is: 6x217x+12\boxed{6x^2 - 17x + 12}
