Question

What’s the first step when rewriting y=3x^2+9x-18 in the form y=a(x-h)^2

Answer 1

Answer:

Steps in rewriting :

y = 3 x² + 9 x - 18 = 3 ( x² + 3 x ) - 18 = 3 (( x² + 3 x + 9/4 ) - 9/4) - 18 = 

= 3 ( x + 3/2 )² - 27/4 - 18 = 3 ( x + 3/2 )² - 99/4

Answer:

3 must be factored from 3 x² + 9 x.
