Answer: -2x^2-12x-17
Step-by-step explanation:
-2(x+3)^2+1 Original equation
-2(x^2+3x+3x+9)+1 factor (x+3)(x+3)
-2x^2-12x-18+1 Multiply the factored part by -2
-2x^2-12x-17 Combine like terms
Step-by-step explanation:
since we are using Pythagoras
c² = a² + b²
with c being the Hypotenuse (the baseline opposite of the 90° angle),

y² = 3² + 3²
so, you pick the ² and put it next to the y left of the "=" sign.
and to the right of the "=" sign you put 3, ², +, 3, ²
