Answer:
Since you are to calculate the value of x, the first thing to do is to collect the like terms, i.e bring all the families of x together.
which implies : x -12x +7x = 7 + 4
-4x = 11
Divide both sides by -4
therefore : x =
Step-by-step explanation:
Step-by-step explanation:
Monomial = x^2, 1 term
Binomial = x^2 + x, 2 terms
Trinomial = x^2 + x + 3, three terms
Binomial is more than 3 terms
Let's do a 3rd degree polynomial like:
- Now let's put parenthesis around (x^3 + 2x^2) and (4x + 8)
- Let's treat both of these as seperate for now. In the first part, you can see an x^2 can be factored out of it
- For example:
- As you can see, if you do the distributive property, it equals the original.
Now let's factor the second part, the 4x + 8. This can be factored by a 4.
Your new equation is:
x^2 + 4 can be factored again down to (x + 2)(x + 2)
YOUR FINAL EQUATION IS:
