Question 1020966
For real zeroes  a and b
y=(x-a)(x-b)
When y=0 (x-intercepts)
(x-a) = 0   , x = a
(x-b) = 0   , x = b
How do the real zeroes relate to the x-intercepts of the quadratic function?
The real zeros a and b are where the quadratic function crosses the x-axis at P(a,0) and P(b,0)
 therefore are the x-intercepts
