Answer:
To convert the vertex form back to standard form, simply square the binomial, distribute a, and add the constants. y=3(x+1)^2+5 y=3(x^2+2x+1)+5 y=3x^2+6x+3+5 y=3x^2+6x+8 This is the original standard form of the equation.
Step-by-step explanation:
5 because 20 divided by 4 is 5, 40 divided by 8 is 5, 60 divided by 12 is 5 and 80 divided by 5 is 16.
