Question

Simplify each expression. −1/2(−40+32x)+(−4+20x)

Answer 1

4x+16

Explanation:

You distribute the -1/2 to the -40 and the 32x. Giving you 20-16x-4+20x. Add both -16x and 20x giving you 4x. Combine 20 and -4 for a positive 16. then you have:

4x+16

Answer 2

4 ( x + 4 )

Explanation:

We know that,

( - ) × ( - ) = ( + )

( + ) × ( + ) = ( + )

( - ) × ( + ) = ( - )

Accordingly, let us solve it.

`\sf-(1)/(2)(-40+32x) +(-4+20x)`

Solve the brackets.

`\sf20-16x-4+20x`

Combine like terms.

`\sf4x+16`

Take the common factor out.

4 ( x + 4 )
