We factor binomials using difference of square formula.
What are binomials?
- Binomials are polynomial that is sum of two terms.
- For example, (x+3), (2x+7)
What is difference of square formula?
a²-b² = (a+b)(a-b)
we can prove this by
⇒(a+b)(a-b)=a(a-b)+b(a-b)
=a²-ab+ab-b²
=a²-b²
How do you factor binomials using difference of square formula ?
It is in the form a²-b² where a=x and b=5
∴ we can write x²-25=x²-5²
=(x+5)(x-5)
