20x^2-17x-2420x217x24

Explanation:

To multiply this you have to multiply the first two terms inside the first parenthesis which are 4x+3x4x+3x by the other two terms 5x-8.5x8.

You multiply 4x * 5x4x5x and then by -88 then you do the same with the 33.

you will get 20x^2-32x+15x-240x232x+15x24 then you combine like terms which are -32x+15x32x+15x and you get 20x^2-17x-2420x217x24.

Hope this helps

Well, the answer is 20x^2 - 17x - 2420x217x24

Explanation:

How to figure it out.

take the equations and do this: (4x + 3) (5x + -8)(4x+3)(5x+8)
(you have to make the equations positive, so make numbers negative)

Multiply (4x) (5x) + (4x) (-8) + (3) (5x) + (3) (-8)(4x)(5x)+(4x)(8)+(3)(5x)+(3)(8)
(distributive property)

20x^2 - 32x +15x -2420x232x+15x24
(add the like properties.)

So the answer is:
20x^2 - 17x - 2420x217x24

Use the distributive property of multiplication.
20x^2 − 17x − 2420x217x24

Explanation:

(4x+3)(5x−8)(4x+3)(5x8)

4x(5x−8) + 3(5x−8)4x(5x8)+3(5x8)

20x^2 − 32x + 15x − 2420x232x+15x24

20x^2 − 17x − 2420x217x24

Apply the property distributive.

Explanation:

The property distributive say that if you have a (c + d)a(c+d) then you can have a*c + a*dac+ad, applying in your problem this same idea we have this result bellow:

(4x+3)(5x-8) = 4x*5x -8*4x + 3*5x - 3*8 = (4x+3)(5x8)=4x5x84x+35x38=

= 20x^2 - 32x + 15x - 24=20x232x+15x24
= 20x^2 -17x - 24=20x217x24
