Question

facterise the following
(1+2x+x²​

Answer 1

Answer:

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

Answer 2

Step-by-step explanation:

${x}^{2} + 2x + 1 = 0 \\ = > {x}^{2} + x + x + 1 = 0 \\ = > x(x + 1) + (x + 1) = 0 \\ = > (x + 1)(x + 1) = 0 \\ = > x = - 1$
