Factor completely: 2x +11x +12?
1 Answer
(2x+3)(x+4)
Explanation:
If you mean:
This simplifies to:
Which factors to:
If you mean
Multiply the coefficient by the constant:
We are trying to find a pair of numbers that add to make
By looking at these pairs we can conclude that
As all terms are positive, all numbers have to be positive
Plugging back in:
Notice that we use the original +12, we only multiply to find the values to factor
Factor the two first terms:
Factor out the last two terms:
One bracket is (x+4), the other is the remaining terms which is
We can always expand to check:
Therefore this is factorised correctly.
