Question 172591
find the intercept And the roots of this equation...
y=20x^2 - 282(x) + 1000 
---
y-intercept: (0,1000)
-----
To find the x-intercepts use the quadratic formula:
20x^2 - 282x + 1000 = 0
10x^2 - 141x + 500 = 0
x = [141 +- sqrt(141^2 - 4*10*500)]/20

x = [141 +- sqrt(-119)]/20

x = [141 +- isqrt(119)]/20
