Answer:
6x
Step-by-step explanation:
x²+9-__=(x-3)²
lets dissosiate this one (x-3)²
(x-3)²=(x-3)(x-3)
=x²-3x-3x+9
=x²-6x+9 so x²+9-6x
so the answer is 6x

Answer:
x = 0
Step-by-step explanation:
Step 1: Write equation
-19 = x - 19
Step 2: Solve for <em>x</em>
- Add 19 to both sides: 0 = x
- Rewrite: x = 0
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-19 = 0 - 19
-19 = -19
