Question
Factor by "splitting the middle"
12x^2 + 11x +2
12x^2 - 4x - 1
Expert Solution
Step 1
Given that we need to do factor of following expressions by using splitting the middle.
12x2 + 11x + 2
12x2 - 4x - 1
Now ,
12x2 + 11x + 2 = 12x2 + 8x + 3x + 2
= 4x ( 3x + 2) + 3x + 2
= (3x + 2) ( 4x + 1)
So,the factors of 12x2 + 11x + 2 are
(3x + 2) and (4x + 1) .
