x(x+1)=x^2+2x+3

Solution

x (x + 1) = x^{2} + 2 x + 3

Solution

x = - 3

Solution steps

x (x + 1) = x^{2} + 2 x + 3

Expand

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

x^{2} + x = x^{2} + 2 x + 3

Subtract

x^{2} + 2 x

from both sides

x^{2} + x - (x^{2} + 2 x) = x^{2} + 2 x + 3 - (x^{2} + 2 x)

Simplify

- x = 3

Divide both sides by

- 1

x = - 3
