Break the expression into groups

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

Factor out

x

from

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

Factor out

- 1

from

- 2 x - 1 : - (2 x + 1)

= x (2 x + 1) - (2 x + 1)

(2 x + 1) : (2 x + 1) (x - 1)

= (2 x + 1) (x - 1)

4 + 7 y = 3 + 8 y

\frac{2 c}{15} = 8.8

\frac{52 !}{( 52 - 4 ) ! 4 !}

\frac{4 - 7 x}{2} = 3 x + 8

12 8^{\frac{6}{7}}
