Answer:
the solution means the answer to whatever question / statement
Answer:
(2x² + 5x + 2) = (2x + 1)(x +2)
Step-by-step explanation:
Given expression is (2x² + 5x + 2).
We have to factorize the given expression.
(2x²+ 5x + 2) = 2x² + 4x + x + 2
= 2x(x + 2) + 1(x + 2)
= (2x + 1)(x + 2)
So the factored form of the given expression will be (2x + 1)(x + 2).
N is a placeholder for a number. In this case, it is 4
We will replace every copy of 'n' with '4' and then simplify
So n+8 turns into 4+8 which simplifies to 12
Is 12 less than or equal to 13? Yes it is. Specifically it is less than 13. So n = 4 is part of the solution set.
Here is how you'd write it all out using algebra



The last inequality is true so the first inequality is true when n = 4. This is another way to see that n = 4 is a solution.
