Answer: 36
Step-by-step explanation:
5(2)+3(-3)-20+3(2)-15(-3)+4
10-9-20+6+45+4
-19+55
36
The vertex is in essence the turning point of the parabola y = x²<span> − 10x + 2
the x coordinate of the turning point = </span>

=

= 5
when x = 5, y = (5)² - 10(5) + 2
= -23
Thus coordinate or vertex is ( 5, -23)
