Question

21x^2-2x+1/21. solve this equation by splitting of middle term​

Answer 1

Answer:

x = 1/21

Step-by-step explanation:

21x²-2x+1/21 = ? , let it's zero

=> 21x²-2x+1/21 = 0

=> 21x²-x-x+1/21 = 0

=> x(21 x-1) -(1/21) ( 21x-1) = 0

=> (21x-1) (x-1/21) = 0

=> x = 1/21

hope this helps you

Answer 2

Answer:

= $21x^{2} -2x + 1/21$

= $21x^{2} -x-x+1/21$

= x ( 21x - 1 ) -1/21 ( 21x - 1 )

= ( x - 1/21 ) ( 21x - 1 )
