दिलेल्या बहुपदीची अवयव काढा: 2x² + x - 1

2 {x}^{2} + x - 1 \\ \\ 2 {x}^{2} + (2 - 1)x - 1 \\ \\ 2 {x}^{2} + 2x - x - 1 \\ \\ 2x(x + 1) - 1(x + 1) \\ \\ (x + 1)(2x - 1) \\ \\

Solution :

Let p(x) = 2x² + x - 1

Splitting the middle term ,

we get

= 2x² + 2x - 1x - 1

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

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

Therefore ,

2x² + x - 1 = ( x + 1 )( 2x - 1 )
