factoring difference of squares trinomial
What is the formula for factoring perfect square trinomials?
Factoring perfect square trinomials: (a + b)^2 = a^2 + 2ab + b^2 or (a - b)^2 = a^2 - 2ab + b^2.
To factor a trinomial using the box method, first place the first term in the first box and the last term in the last box.
Then multiply the first and last box.
Find two terms which are the product of the first and last box, and which add up to be the middle term.
Place these terms into the remaining boxes.
What is the rule for factoring the difference of squares?
The general formula for factoring a difference of squares is a 2 − b 2 = ( a + b ) ( a − b ) .
For example 9 x 4 − 25 = ( 3 x 2 + 5 ) ( 3 x 2 − 5 ) .
How do you factor a trinomial?
Factorizing with GCF
1Write the trinomial in descending order, from highest to lowest power.2) Find the GCF by factorization.
3) Find the product of the leading coefficient 'a' and the constant 'c.
4) Find the factors of the product 'a' and 'c'.
5) Rewrite the original equation by replacing the term “bx” with the chosen factors.
