(-2x-1)^2=0 How to solve brackets, please help
malfutka [58]
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.

X²+2xy+y²=144, (x+y)³?​
Bumek [7]

Answer:

The value of (x + y)³ is 1728.

Step-by-step explanation:

First, you have to find the value of x + y :

x² + 2xy + y² = 144

x² + xy + xy + y² = 144

x(x + y) + y(x + y) = 144

(x + y)(x + y) = 144

(x + y)² = 144

x + y = √144

x + y = 12

Next, the value of (x + y)³ :

(x + y) = 12³ = 1728
