X->​

Answer 1

( x+1 ) (2x+1 )

so its answrr iss

4x+2 .

6x

is the answer

Answer 2

Answer:

Here is your answer .

Step-by-step explanation:

$(x + 1)(2x + 1) \\ 2 {x}^{2} + x + 2x + 1 = 0 \\ 2 {x}^{2} + 3x + 1 = 0 \\ 2 {x}^{2} + 2x + 1x + 1 = 0 \\ 2x(x + 1) + 1(x + 1) = 0 \\ (x + 1)(2x + 1) = 0 \\ x + 1 = 0 \: or \: 2x + 1 = 0 \\ x = - 1 \: \: or \: \: 2x = - 1 \\ x = - 1 \: or \: x = \frac { -1}{2}$

x = -1 or x = -1/2
