Which equation is y = (x + 3)2 + (x + 4)2 rewritten in vertex form?

vertex form

Step-by-step explanation:

Lets square the terms

Now use completing the square method to get the vertex form

to apply the method we need to take out 2

WE take middle term , divide it by 2 and square it . then add and subtract it

square it

Add and subtract the fraction

Take out -49/4 and multiply with 2 , then add it with 25

answer:     true

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
