18x^2-(9x+2)(2x-1)=1

18 x^{2} - (9 x + 2) (2 x - 1) = 1

x = - \frac{1}{5}

Decimal Notation

x = - 0.2

Solution steps

18 x^{2} - (9 x + 2) (2 x - 1) = 1

Expand

- (9 x + 2) (2 x - 1) : - 18 x^{2} + 5 x + 2

18 x^{2} - 18 x^{2} + 5 x + 2 = 1

Add similar elements:

18 x^{2} - 18 x^{2} = 0

5 x + 2 = 1

2

to the right side

5 x = - 1

Divide both sides by

5

x = - \frac{1}{5}
