Question

Use the technique of completing the square to transform the quadratic equation into the form (x+c)2=a 25x-100x-275=0

Answer 1

i think u miss x in either 25(which should be 25x^2 ) or in the 100(which should be 100x^2)?

Answer 2

it is 25x^2

Answer 3

25x^2-100x-275
25(x^2-4x)-275
25(x-2)^2-275-25(4)
25(x-2)^2-375

Answer 4

let me know if you need help understanding what I did.

Answer 5

shouldnt 25 be to the second power

Answer 6

yes it is i messed that up

Answer 7

@Gunsy do you understand what I did?

Answer 8

sort of

Answer 9

25x2 -100x -275 =0
divide all by 25
x^2 -4x - 11=0
x^2 -4x = 11
dive -4 by 2 which is equal to -2 then square it, it will be 4, now add this number to both sides
x^2 -4x +4 = 11+4
(x - 2) ^ 2 = 15

hope it is clear

Answer 10

that i understood Sam

Answer 11

i have another one as well 5x^2-100x+455=0 Using the technique of completeing the square to transform the quadratic equation into form (x+c)^2=a

Answer 12

if you understood the last one, just do the same thing. If not ask a question. we should not just do them all for you..not that you are asking us to.

Answer 13

it would be (x-10)^2=9 correct??
