simplify-2(x+1)^2+(x+1)-1

simplify

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

- 2 x^{2} - 3 x - 2

Solution steps

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

Apply rule:

a + (b + c) = a + b + c

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

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

Subtract the numbers:

1 - 1 = 0

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

Expand

- 2 (x + 1)^{2} : - 2 x^{2} - 4 x - 2

= - 2 x^{2} - 4 x - 2 + x

Group like terms

= - 2 x^{2} - 4 x + x - 2

Add similar elements:

- 4 x + x = - 3 x

= - 2 x^{2} - 3 x - 2
