For Problems 63 – 84, factor each polynomial completely. Indicate any that are not factorable using integers.
The factorization of the given polynomial.
To factorize the trinomial in the form: ax2 + bx + c
1) Factor out common factor from all the terms.
2) Find the product of 1st and last term (a×c).
3) Find the factors of ac in such way that addition or subtraction of those factors is the middle term.
4) Write the center term using the sum of the two new factors, including the proper signs.
5) Group the terms to form pairs - the first two terms and the last two terms. Factor each pair by finding common factors.
6) Factor out the shared (common) trinomial parenthesis.
7) By the formula of difference of two squares,
Use middle term splitting method.
Use formula of difference of two squares,
Substitute u = t and v = 5 in
