Best ResponseYou've already chosen the best response.1is the original problem 21x^258x21 ?

hartnn

Best ResponseYou've already chosen the best response.1right,so thats 21x^240x21=0 right ?

Best ResponseYou've already chosen the best response.1yeah and then the product of 21 and 21 is 441 and then 40 so the two numbers are 49 and 9

Best ResponseYou've already chosen the best response.1that is correct, see above u have written 49x  9x instead of what u got now as 49x+9x

Best ResponseYou've already chosen the best response.1now whats common from first 2 terms in 21x^249x9x21 =0?

Best ResponseYou've already chosen the best response.1Compare your quadratic equation with \(ax^2+bx+c=0\) find a,b,c then the two rots of x are: \(\huge{x=\frac{b \pm \sqrt{b^24ac}}{2a}}\)

Best ResponseYou've already chosen the best response.1oh wait nooo i gave you the wrong equation! no wonder

eli123

Best ResponseYou've already chosen the best response.1but in that equation it says b so (9) is 9

Best ResponseYou've already chosen the best response.1inside i did put put 9^2 = 81

hartnn

Best ResponseYou've already chosen the best response.1yes, u are correct \(\huge\frac{9 \pm \sqrt{1}}{4}=\frac{10}{4},\frac{8}{4}\)

Best ResponseYou've already chosen the best response.1do u want to factor or do u want to use quadratic formula? anyways its not factorable....

eli123

Best ResponseYou've already chosen the best response.1so what would be the answer?

hartnn

Best ResponseYou've already chosen the best response.1all u can do is \(2 \pm \sqrt7\)

eli123

Best ResponseYou've already chosen the best response.1how does that equal to that

hartnn

Best ResponseYou've already chosen the best response.1\(\sqrt{28}=\sqrt{7*4}=\sqrt{7}\sqrt{4}=2\sqrt{7}\)
