What are the factors of X² 6x 9?

Look: (x + 3)² = x² + 6x + 9, and (x – 3)² = x² – 6x + 9! Here 9 can be written as (−3)², so the middle term is 2(−3)x = −6x. So when the sign of the middle term is negative, the trinomial may be factored as (a – b)².
…

What is the answer of X² 9?

Solve using the Square Root Property.

Don’t forget to use both positive and negative square roots! Notice that there is a difference here in solving x² = 9 and finding . For x² = 9, you are looking for all numbers whose square is 9. For , you only want the principal (nonnegative) square root.

Which expression is a factor of 36×2 − 49?

Algebra Examples

Rewrite 36×2 36 x 2 as (6x)2 ( 6 x ) 2 . Rewrite 49 as 72 . Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 – b 2 = ( a + b ) ( a – b ) where a=6x a = 6 x and b=7 .

Why is 49 a perfect square?

The square root of 49 is obtained by the number whose square gives the original number. The answer obtained on squaring 7 is 49. Hence, 49 is a perfect square.
