Write the quadratic equation y=x^2-6x+7 in vertex form

Using the formula x = b/(-2a) to find the x of the vertex you can find y of the vertex and plug into y = a(x - h)² + k where (h, k) is the vertex

h = x = -6/(-2×1) = 3
k = y = (3)² - 6(3) + 7 = -2
a = 1 because it is the coefficient of x² in y = ax² + bx + c

y = (x - 3)² - 2

If is was sunny on thursday, chances are that it will be a sunny if friday depending on the degrees and temperature. your welcome!
