( ^ = to the power of )
it can be
6x^2+5x – 6
or
6x^2+13x – 6
or
6x^2– 5x – 6
or
6x^2– 13x – 6
thank you!!

Start with the left term in each expression
3x x 2x = 6x^2
Then the outsides
3x x -3 = -9x
Then the insides
2 x 2x = 4x
then the left terms
2 x -3 = -6
So, you get 6x^2 - 9x + 4x -6
Combine like term
6x^2 -5x - 6
Clear?

multiply to get the answer. use FOIL. This stands for first, outer, inner, last. multiply the first two numbers, 2x and 3x, then multiply the outer numbers, 3x and -3, then the inner ones, 2x and 2, and finally, the last ones, 2 and -3. you come out with 6x^2-9x+4x-6.
Simplify that to get:
6x^2 - 5x - 6
Hope this helps you out!

Simplifying
(3x + 2)(2x + -3)
Reorder the terms:
(2 + 3x)(2x + -3)
Reorder the terms:
(2 + 3x)(-3 + 2x)
Multiply (2 + 3x) * (-3 + 2x)
(2(-3 + 2x) + 3x * (-3 + 2x))
((-3 * 2 + 2x * 2) + 3x * (-3 + 2x))
((-6 + 4x) + 3x * (-3 + 2x))
(-6 + 4x + (-3 * 3x + 2x * 3x))
(-6 + 4x + (-9x + 6x^2))
Combine like terms: 4x + -9x = -5x
(-6 + -5x + 6x^2)
answer is 6x^2– 5x – 6

The answer is obtained by rewriting it as
3x(2x - 3) + 2(2x - 3)
which gives 6x^2 - 9x + 4x - 6 i.e. 6x^2 - 5x - 6.

just multiply them
(3x + 2)(2x - 3)
6x^2 - 9x + 4x - 6
6x^2 - 5x - 6
