If we firstly consider only the terms in x.
subtract 2x from both sides of the equation
⇒5+2x
−2x=2x−2x
+6
Observe that the x terms are eliminated and we are left with
5+0=0+6 that is 5=6 which is invalid
There is no solution to this equation.
Answer: I did it in the explanation thingy-
Step-by-step explanation:
Step 1. 8792 - 6886 = 1906
Step 2. 12 x 9 108
That... OR the answer is 205848X

This is the theorem that I use, so to expand, you multiply the first number in the equation so it would be w times w because in (w-9) and (w+3) w is the first term. So now you do the outer number which is the first and last number in the equation which is w and 3 and we multiply them together. now we do the inner, which are the two inner terms, which are -9 and w and we multiply them. Now we do the last terms in each ( ) which is -9 and 3 and we multiply them. This is kinda hard to get used to, but it helps so much when you are trying to expand trinomials that are multiplied together!
so we add all the answers we got for first, outer, inner and last numbers
w*w+w*3+-9*w+-9*3
w2+3w-9w-27
w2-6w-27
Hope that helps :)
