20x^2-17x-24

Explanation:

To multiply this you have to multiply the first two terms inside the first parenthesis which are 4x+3x by the other two terms 5x-8.

You multiply 4x * 5x and then by -8 then you do the same with the 3.

you will get 20x^2-32x+15x-24 then you combine like terms which are -32x+15x and you get 20x^2-17x-24.

Hope this helps

Well, the answer is 20x^2 - 17x - 24

Explanation:

How to figure it out.

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

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

20x^2 - 32x +15x -24
(add the like properties.)

So the answer is:
20x^2 - 17x - 24

Use the distributive property of multiplication.
20x^2 − 17x − 24

Explanation:

(4x+3)(5x−8)

4x(5x−8) + 3(5x−8)

20x^2 − 32x + 15x − 24

20x^2 − 17x − 24

Apply the property distributive.

Explanation:

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

(4x+3)(5x-8) = 4x*5x -8*4x + 3*5x - 3*8 =

= 20x^2 - 32x + 15x - 24
= 20x^2 -17x - 24
