Question

How do I simplify this?

((−(4 x))−5) (3 x−9)

Answer 1

Hi there!

To simplify is, well, simple.

Here is what you need to do:

((-(4x))-5)(3x-9)
= (-4x+-5)(3x+-9)
=(-4x)(3x)+(-4x)(-9)+(-5)(3x)+(-5)(-9)
=-12x²+36x-15x+45
=-12x²+21x+45

Your answer simplified is
-12x²+21x+45

Hope this helps!

Answer 2

(−4x−5)(3x−9)=
(−4x+−5)(3x+−9)=
(−4x)(3x)+(−4x)(−9)+(−5)(3x)+(−5)(−9)=
−12x2+36x−15x+45=
−12x2+21x+45
