If <span>a ≥ 0</span><span> then </span><span>√a</span><span> denotes the non negative square root of </span>a<span>.

</span><span>(x-9)^2 = (-(x-9))^2
</span>
So both <span>x−9</span><span> and </span><span>−<span>(x−9)</span></span><span> are square roots of </span><span><span>(x−9)</span>2</span><span>, but we want to pick whichever is non negative.

x−9</span>|</span><span> does that for us.

Five dozen cds were bought for $90 a peddlar sold them at 5 for $12 calculate his profit.
valina [46]
If 12 dozen were bought for $90 that means each CD was bought at the price of $0.66

If he sold all 60 of the CD's for 5 for $12, he'd make $144. 

Subtract the income by the original buying price to find his profit. $144 - $90

The peddler made $54 profit.

\rm \looparrowright -  \frac{1}{4} (8 - 4 + 20x)

Subtract the numbers

\rm \looparrowright -  \frac{1}{4} (4+ 20x)

Factor out 4 from the expression

\rm \looparrowright   - \frac{1}{ \cancel4}  \times  \cancel4(1 + 5x)

\rm \looparrowright   - (1 + 5x)

When there is a - in front of an expression in parentheses, change the sign of each term in the expression to -

\rm \looparrowright   - 1  -  5x
