Answer:
6x² - 2x + 1
Let's use the AC Method.
First multiply the coefficient ( A=6 ) of the x² term by the coefficient ( C=2) of the constant term - ignoring the sign.
AC=6⋅2=12
Notice that the sign of the constant ( C ) term is negative.
According to the AC Method, we need to look for
a factorisation of our AC
value into a pair of factors, whose difference is the middle coefficient B=1
Well 4×3=12 and 4−3=1
So the pair we want is 4 and 3
Now use this pair to split the middle term then factor by grouping:
6x²−x−2=6x²−4x+3x−2
=(6x²−4x)+(3x−2)
=2x(3x−2)+(3x−2)
=(2x−1)(3x−2)
