So you are saying that you want to find out what it would be in simple from.
(a 2n-a n-6) (a n+8)
a²n²+2an-48
Is there any sign between 12 and -17 on the left side?
if no, then this is to be interpreted as a multiplication and is equal to -204.
so we have -204=-17+k
which means
-204+17=k
-187=k
so k is -187
if thre is a plus between the 12 and (-17) then k would be 12 (and both sides of the equation would be essentially the same, just inverted order)
4y2=256
4 x 2 = 8
256 divided by 8
Y=32
The error is that if the absolute value your looking for is a positive number, you wouldn't have to change and the sign.
Answer: y = -2x² + 920x - 84168
suppose: the equation of the parabola is y = ax² + bx + c
because the parabola passes through (126,0); (134,3200); (334,0)
=> we have the equations:
126².a + 126b + c = 0
134².a + 134b + c = 3200
334². a + 334b + c = 0
⇒ a = -2
b = 920
c = -84168
=> the equation of the parabola is y = -2x² + 920x - 84168
