Question

48x2-13x-1=0 solve by factorisation method​

Answer 1

Answer:

48X2-13X-1=0

48X2+3X-16X-1=0

3X[16X+1]-1[16X+1]

[16X-1]  [16X+1]

EITHER

16X-1=0                            16X+1=0

X=-1/ 16    OR   X=1/3

Answer 2

48x² – 13x – 1 = 0

48x² – 16x + 3x – 1 = 0

16x ( 3x – 1 ) + 1 ( 3x – 1 ) = 0

( 3x – 1 ) ( 16x + 1 ) = 0

since. product of two numbers is zero hence

3x – 1 = 0

3x = 1

x = 1/3

or

16x + 1 = 0

16x = – 1

x = –1 / 16
