Answer:

Step-by-step explanation:

divide by 2 and square it

y+axSQUARED +bx+ c ----->(b/2)squared +d

2 ) add and subtract d to the equation

y = (axSQUARED +bx +d ) + c -d

factor the first part of the equation to match the vertex form and simplify

y= a(x-h)SQUARED + c- d

Y = a ( x - h SQUARED + k
