Solve x^2 + 4x - 10 = 0 please @pooja195
Hi there ;) Welcome to Question Cove Any ideas as to where we should start?
Hmm factoring is not going to work here, we will need to use the quadratic formula which looks like this: \[\huge~\rm~x=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\] \(\normalsize\color{ slate }{{\bbox[5pt, lightcyan ,border:2px solid black ]{ \LARGE{x=~} \huge{ \frac{-\color{magenta}{b} \pm\sqrt{ \color{magenta}{~b} ^2-4 \color{blue}{a} \color{red}{c}~}}{2 \color{blue}{a}} }~ }}}\) when the equation is \(\large\color{black}{ \color{blue}{a} x^2+ \color{magenta}{b}x+ \color{red}{c}=0 }\). Are you familiar with this?
Hot dayum, lol. Yes I am familiar with that.
Can you tell me the a,b,c values? :P
a is 1, b is 4, c is -10

Wow, I got my answer of \[-2\pm \sqrt{14}\] Thanks Pooja.
