Step-by-step explanation:
Factoring polynomials by splitting the middle term:
We need to find two numbers ‘a’ and ‘b’ such that a + b =-7 and ab = 12.
On solving this we obtain, a = 4 and b = 3
Thus, the above expression can be written as:
12x2 -7x + 1
= 12x2 – 4x – 3x + 1
= 4x(3x – 1) -1 (3x – 1)
= (3x -1)(4x – 1)
Thus, 3x – 1 and 4x – 1 are the factors of the polynomial 12x2 -7x + 1
