do you know how to complete the square ?

hartnn Group TitleBest ResponseYou've already chosen the best response.2
x^2+4x = 21 here, the coefficient of 'x' is 4 so, divide it by 2, and take its square, what u get ?

4/2=2 square root is 1.4

hartnn Group TitleBest ResponseYou've already chosen the best response.2
we need to SQUARE the result so, 2^2 = 4 now, we add this on both sides., x^2+4x+4 = 21+4 = 25 got this ?? notice something about left side ?

x^2+4x+4 is square of what ?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
4 is the square of 2 x^2+4x+4 will be square of \(\large (x+2) \\ (x+2)^2 =x^2+4x+4\) so we have \((x+2)^2=25\) take square root of both sides , what u get ?

hartnn Group TitleBest ResponseYou've already chosen the best response.2
yes.. just put +/ in front of 5 x+2=5 or x+2=5

Does x2 = x^2 And does the = sign suppose to be a + sign?

sorry im still waking up x^2=183x

it is morning hear its 8:30 am

hartnn Group TitleBest ResponseYou've already chosen the best response.2
so, split up, 3x = 6x3x \(x^2+6x3x18=0\) factor out x from 1st 2 terms and 3 from last 2.....can you ?

(x+6)(x3) i think
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
there's no  *minus* sign \((x+6)(x3)=0\) is correct final answer! good :)
