Factor completely 9x2 42x 49. (3x 7)(3x − 7) (9x − 7)(9x − 7) (3x 7)(3x 7) (9x 7)(9x 7).
1 answer:
Factors of the given expression by splitting middle term of expression will be
.
Given expression is
A factor is a number that divides another number leaving no remainder
After we split 42x into 21x each,
The expression looks like,
Taking 3x+7 as common
So factors will be (3x+7) and (3x+7).
Therefore,
Factors of the given expression will be
.
