Simplify each expression

6x+(5x-8)

-(2-x)-3(6+8x)-12

11-(3x-6)+2(4x+5)-x

(x+-2)-12x

- show work-

1) 6x+(5x-8)

Now combine like term

11x-8

2) (2-x)-3(6 + 8x)-12

distribute the negative sign and the -3

-2 + x - 18 - 24x - 12

then you have to combine like terms

-23x - 32

3) 11-(3x-6)+2(4x+5)-x

11-(3x-6)+8x+10x

11-3x+8x+10x

11-21x3

4) actually i don't know number 4 .

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
