Not quite sure what you mean by brackets, but you can get the solution to this equation in a few steps:
<span>(-2x - 1)</span>² <span>= 0 ... square root both sides to eliminate the squared binomial
</span>√(-2x - 1)² = √0 ... simplify; the square is canceled out and the root of 0 brings you back to 0
-2x - 1 = 0 ... solve like a two-step equation
-2x = 1
x = -1/2 is your x-value.

Step-by-step explanation:
1275 divided by 15=$85 each
To multiply two fractions, we multiply the top number (numerators) together and the bottom numbers together (denominators) and then simplify.
8 x 5 = 40
15 x 6 = 90
40/90 can be simplified (÷10) to 4/9
