Asked by Alaska Diamond
can anyone show me steps in solving for x
-49x^2 + 4606x - 52,000 = 42,080
thank you
-49x^2 + 4606x - 52,000 = 42,080

Start by setting the equation equal to 0:
0 = 49x^2 - 4606x + 52000 + 42080
0 = 49x^2 - 4606x + 94080
Dividing each term by 49, we have:
0 = x^2 - 94x + 1920
This will factor easily:
0 = (x - 64)(x - 30)
Set each factor equal to 0:
x - 64 = 0; x = 64
x - 30 = 0; x = 30
These are your two possible solutions for x.
I hope this helps.
