Find the vertex form of y=(x+2)(x-3)

y = (x - )² -

Step-by-step explanation:

Given

y = (x + 2)(x - 3) ← expand factors

  = x² - x - 6

Use the method of completing the square

add/ subtract ( half the coefficient of the x- term )² to x² - x

y = x² + 2(- ) x + - - 6

  = (x - )² -

step-by-step explanation:
