$$(w-4)(w-9)\\\\
=w(w-9)-4(w-9)\\\\
=w^2-9w-4w--36\\\\
=w^2-13w+36\\\\$$

-28y(y-8)

$$-28y*y--28y*8\\\\
=-28y^2+28*8y\\\\
=-28y^2+224y$$

Thank you for your good manners!

12x(x-11)

The same way as all the other.  Are you actually trying to learn something here or am I just doing all your homework?

$$12x(x-11)\\\\
=12x*x-12x*11\\\\
=12x^2-132x$$

Happier now - I copied the question wrongly.

What you need to do is multiply the number which is in front of the ( & ) with that what is in it, -12y(y-6):

Multiply y with -12y, that's -12y^2. muliply -6 with -12y that's 72y (negatif x negatif is positif), so -12y^2 + 72y and than futher as has been shown in the past answers

The answer to the one that's wrong is: 12x(x-11) = 12x^2 - 132x = x(12x-132) but that last step isn't necesary

if in the test was: 12x(x-11)=0, you also have to say:

x=0 v x=12x-132

x=0 v 12x=-132

x=0 v x=-11

Yay! Let's all state our country of residence and tongue!

 

I live in America, have somehow no accent at all, and am Korean. My tongue is an average amount of slimy and length.

I don't think that the English or the Americans say 'mate'.

Zegroes will tell you that you are not allowed to use it.  

He says only I can, but I think other Aussies are allowed to use it too.  lol.
