4x(3x − 7) − 19x2 the 2 behind the x is an exponent
1 answer:
Answer:
-7x(x + 4)
Step-by-step explanation:
Not sure exactly what you're doing with this, but I know you're not solving it for x because there's no " = " there so I am assuming you're simplifying it as much as possible. I'm going with that.
First thing is to distribute through the parenthesis by multiplying 4x by 3x and then 4x by -7 to get:
Now combine like terms to get
The last thing you could do now is pull out what's common between each of those terms which is -7x. When you do that, you're left with
-7x(x + 4)

Answer:
Step-by-step explanation:
To find this equation in standard form, first, write it in factored form. This looks like . Then, multiply the polynomials using the FOIL (First, Outside, Inside, Last) method.
- Following the FOIL method, you should multiply the first terms in each binomial,
, which equals
.
- Then, the outside terms,
. This equals
.
- Next, the inside terms,
.
- Finally, the last terms,
, this equals
.
Then, add all of the terms together . To get the standard form, combine like terms, this comes out to
.
