PERFECT SQUARE TRINOMIAL
Question: The trinomial [tex]x^{2} -22x+121[/tex] if written as a square of a binomial is
[tex]A.\:(x+11)[/tex]
[tex]B.\:(x+22)[/tex]
[tex]{\boxed{C.\:(x-11)}}[/tex]
[tex]D.\:(x-22)[/tex]
Answer:
[tex]{\red{\boxed{\red{\huge{\boxed{\sf{(x-11)}}}}}}}[/tex]
=====================================
PERFECT SQUARE TRINOMIAL
- Check that the middle term is two times the product of the numbers being squared in the first term and third term.
=====================================
Steps and Solution:
Factor using the perfect square trinomial rule.
[tex]{\tt{a^{2}-2ab+b^{2}=(a-b)^{2}}}[/tex]
Where [tex]a=x[/tex] and [tex]b=11[/tex]
[tex]{\tt{(x-11)^{2}}}[/tex]
