someone help me please ... 9x^2+4x+5=0 solve
Okay. What method are you comfortable with? Factoring? Quadratic formula?
whatever ... just solve it ...
Though, I'd suggest the formula here.\[x = {-b \pm \sqrt{b^2 - 4ac} \over 2a} \]
\[\implies x = {-4 \pm \sqrt{4^2 - 4(9)(5)} \over 2(9)} \]Can you solve it?
does lovebird know wht a,b,c are? O.o
Okay.. wait.. \(9x^2 + 4x + 5 = 0\) a b c
\(a\) is the coefficient of \(x^2\). \(b\) is the coefficient of \(x^1\) \(c\) is the coefficient of \(x^0\) or \(1\).
oh then what can i doo @ParthKohli : i like you ... thnx :D
Okay, so can you continue with that? Thanks!
noo i cant .... help me
i suck at maths
Okay.\[x = {-4\pm \sqrt{4^2 - 4(9)(5)} \over 2(9)} \]\[x = {-4 \pm \sqrt{16 - 180} \over 18} \]\[x = {-4 \pm \sqrt{-164} \over 18} \]Before continuing, do you know what \(\pm\) is?
yes i know that
