Question

do with the quadratic formula or equation.
x^2 + 4x + 4 = 7????

Answer 1

That sets up nicely for factoring

Answer 2

I would always try to factor first just because its faster personaly i only use the quadratic if I have to

Answer 3

my teacher told me to put it into a=1 b=4 c= - 3 form or something and then put it into the equation (i know what the equation is im just stuck)

Answer 4

ok then it sounds like you are going to have to do it with the quadratic.

Answer 5

I agree, I didn't see the 7

Answer 6

subtract both sides by 7 then you get x^2=4x-3 a=1 b=4 c =-3 use qaud eq x=(-b+/-sqrt(b^2-4ac))/(2a)

Answer 7

i keep coming up with -2 + or - radical 7

Answer 8

is that wrong or right im confused

Answer 9

That looks like it would do it.

Answer 10

did you apply the formula correctly? If you did, you should get the right answer.

Answer 11

o okay thank u so much!

Answer 12

should get (-4+sqrt28)/2 and (-4-sqrt28)/2

Answer 13

\[-2\pm \sqrt{7}\]

Answer 14

i got what radar said. not eric8 ahh which one is right

Answer 15

I think EricC8 can be simplified for example the 28 is 7 x 4 and the sq root of 4 could be taken out of the radical

Answer 16

o okay thank u so much!

Answer 17

then the denominator 2 could be divided into each term

Answer 18

oh i see what you mean

Answer 19

By Jove I believe you've got it!
