Answer: 24
====================================================
Work Shown:
Everywhere you see an x, replace it with 5.
Then use PEMDAS to simplify.
y = 4*(x-2)*(x-3) + 7*(x-2)*(x-5) - 6*(x-3)*(x-5)
y = 4*(5-2)*(5-3) + 7*(5-2)*(5-5) - 6*(5-3)*(5-5)
y = 4*(3)*(2) + 7*(3)*(0) - 6*(2)*(0)
y = 24 + 0 - 0
y = 24
This means,
4*(x-2)*(x-3) + 7*(x-2)*(x-5) - 6*(x-3)*(x-5) = 24
when x = 5
