Question

HELP PLEASE?! ANYONE ): What term do you need to add to each side of 3x^2 + 15x = 3 to complete the square?

Answer 1

if we factor out the 3 on the left; we can do this the usual way after wards

Answer 2

the choices are 25/4 , 15/2, 2/15, or 4/25 ... i had thought the same same thing but...?

Answer 3

3x^2 + 15x = 3

3(x^2 + 5x) = 3

3((x+n)(x + 5)) = 3

i just factor it as tho its complete, then split the difference between the two parts; n=5/2

3((x+5/2)(x + 5/2)) = 3

3 (x+5/2)^2 = 3

this tells me that the value to complete the square is 3(5/2)^2

Answer 4

where did u get n from?

Answer 5

its one of those letter in the alphabet; its just a place filler as i finish it up
