simplify x(3x-2)-(3x+2)(3x-2)

simplify

x (3 x - 2) - (3 x + 2) (3 x - 2)

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

Solution steps

x (3 x - 2) - (3 x + 2) (3 x - 2)

Expand

x (3 x - 2) : 3 x^{2} - 2 x

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

Expand

- (3 x + 2) (3 x - 2) : - 9 x^{2} + 4

= 3 x^{2} - 2 x - 9 x^{2} + 4

Group like terms

= 3 x^{2} - 9 x^{2} - 2 x + 4

Add similar elements:

3 x^{2} - 9 x^{2} = - 6 x^{2}

= - 6 x^{2} - 2 x + 4
