Question

4x^2-1 by splitting the middle term

Answer 1

Heya !!!




4X² -1



(2X)² - (1)²




( 2X + 1) ( 2X - 1) = 0





( 2X +1) = 0 OR (2X -1) = 0




X = -1/2 OR X = 1/2

Answer 2

$Heya$‼


$4x^2-1$

$=(2x)^2-(1)^2$


As we know,
$a^2-b^2=(a-b)(a+b)$



$Continuing\:our\:solution:-$

$=(2x-1)(2x+1)$

$=>(2x-1)=0\:or\:(2x+1)=0$

$=>x=\frac{1}{2}\:or\:x=\frac{-1}{2}$
