$-8 + 40x$

$-8(1-5x)$

$=(-8)(1) + (-8)(-5x)$

$=-8 + 40x$

$-8 + 40x$

The parentheses tell us that we multiply all the terms by the outside factor.

So $-8(1-5x)$ is really $-8 xx 1 - (-8 xx 5x)$

NOTICE how I put the "stuff" after the subtraction sign into parentheses. That's because we need to simplify $-8$ and $5x$ before we subtract it

$-8 - (-40 x)$

$-8 + 40x$

How do you simplify -8(1-5x)-8(1-5x)?
