Question

Simplify: 2x(x + 18) − x(4x − 2)

Answer 1

\[\large{2x(x+18)}\]

first solve for this

Answer 2

2x(x+18) = 2x(x)+2x(18)

can you tell me what do you get?

Answer 3

2x^2+36x=2x^2+36x

Answer 4

ok good .. now solve for -x(4x-2)

Answer 5

-4x^2-2x

Answer 6

first term is right but second term :

-x(4x-2)
-x(4x)-x(-2)

-4x^2 + 2x

Answer 7

there will be + ..

Answer 8

oooh, soo what do i do after i do all that

Answer 9

now :
\[\large{2x^2+36x-4x^2+2x}\]
\[\large{2x^2-4x^2+36x+2x}\]

Answer 10

can you do it now?

Answer 11
