Question

factorise 12x^2 - 7x +1​

Answer 1

Answer:

12x²-7x+1=0

Comparing the above equation with

ax²+bx+c=0..... (General form)

here,.

a=12 , b=-7 , c=1

b²-4ac=(-7) ²-4×12×1

=49-36

=13

therefore,

x=-b±√b²-4ac/2a ..... ( Formula method)

x=7±√13/24

x=7+√13/24 OR 7-√13/24.

12x²-4x-3x+1

= 4x(3x-1)-1(3x-1)

= (3x-1)(4x-1)
