Answer:

Simplified equation in standard form:
y=(1)/(4)x^(2)+12(1)/(4)

Original equation in standard form:
y=1/2(x+3)^2+10

Explanation:


y=(1)/(2)(x+3)^2+10

Step 1: Distribute the
(1)/(2) :


y=((1)/(2)*x+(1)/(2)*3)^2+10


y=((1)/(2)x+1(1)/(2))^2+10

Step 2: Take
((1)/(2)x+1(1)/(2)) and square it :


y=((1)/(2)x+1(1)/(2))^2+10


y=((1)/(2)x)^(2) +(1(1)/(2))^2+10


y=((1)/(2)x*(1)/(2)x)+(1(1)/(2)*1(1)/(2))+10


y=(1)/(4)x^(2)+2(1)/(4)+10

Step 3: Add the constants:


y=(1)/(4)x^(2)+(2(1)/(4)+10)


y=(1)/(4)x^(2)+(12(1)/(4))

Step 4: Get rid of the parenthesis:


y=(1)/(4)x^(2)+12(1)/(4)
