Hi,

I have pasted solution here:


Explain how to factor the following trinomials forms: x^2 + bx + c and ax^2 + bx + c. Is there more than one way to factor this? Show your answer using both words and mathematical notation.

Solution:
---------
There are different methods for factoring x^2 + bx + c and ax^2 + bx + c.

Factoring x^2 + bx + c:
----------------------

To factor x^2 + bx + c, find integers m, and n such that
Then we can write it as

x^2 + bx + c = (x+m)(x+n)
x^2 + bx + c = x^2 + (m+n)x + mn

So the sum of m and n should be equal to b and product of m and n should be equal to c.


Factoring ax^2 + bx + c:
-----------------------

To factor ax^2 + bx + c, a ≠ 1, find integers k, l, m, and n such that

ax^2 + bx + c = (kx+m)(lx+n)
ax^2 + bx + c = klx^2 + (kn + lm)x + mn

Therefore, k and l must be factors of a and m and n must be factors of c.
