rewrite x^2-12x+ 15 in the form (x -a)^2 +b, and hence solve the equation x^2-12x+15=0, giving your answer in exact form.​

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

i honestly dont know

35/2 is it i think maybe
