Complete the square
factor out linear coefient
f(x)=7(x^2+6x)
take 1/2 of linear coefient and square it and add negative and positive to inside
6/2=3, 3^2=9
f(x)=7(x^2+6x+9-9)
complete squre
f(x)=7((x+3)^2-9)
expand
f(x)=7(x+3)^2-63 is veretx form
vertex is (-3,-63)
It wouldn’t let me cancel to answer this but i do not know the answer and i had to type something to exit it. i’m sorry
