Help please Find the x-intercepts for the parabola defined by the equation below.
y= x^2-9x+ 18
A. (-3,0) and (-6,0)
B. (0, -3) and (0, -6)
c. (0,3) and (0,6)
D. (3, 0) and (6.0)

The answer correct (D).

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
