Answer:
16
Step-by-step explanation:
To solve this equation, we need the formula for perfect squares:
or
<em>this is the formula we will use because the signs match the one in the question</em>.
Knowing these, we can set up an equation that assumes that the answer we will end up with is a perfect square.
Work:
- this is the setup for being able to solve for the unknown
, now we need to solve for .
(I replaced 
with 
because I'm setting up this question to be a perfect square).
- multiply the left side. Remember that your answer will not be
, but 
.
- Divide like terms and isolate the variable. In this case,
and 
are on both sides, so dive them and they will be canceled out.
- divide by
and you will have your value for .
- Now we plug into our original equation equation for perfect squares.
Our final answer is 16.
12-x=15 subtract both side
-12 -12
—————
-x=3
— —divide both side to get the “X”
-1 -1
The answer is
X=3
