Question

simplify {x+1} {x+1}

Answer 1

Method 1

( x + 1 ) ( x + 1 )  is like  a × a = a²

Using Identity A × A = A²

⇒ ( x + 1 ) ( x + 1 )

⇒ $( x + 1 )^{2}$

Using Identity ( a + b )² = a² + 2ab + b²

⇒ ( x + 1 )²

⇒ x² + ( 2 × x × 1 ) + 1²

⇒ x² + 2x + 1

∴ Simplified Answer ⇒⇒⇒  x² + 2x + 1

Method 2

⇒ ( x + 1 ) ( x + 1 )

⇒ x ( x + 1 ) + 1 ( x + 1 )

⇒ x² + x + x + 1

⇒ x² + 2x + 1

∴ Simplified Answer  ⇒⇒⇒  x² + 2x + 1
