Question

solve using formula 5m^2-2m=2​

Answer 1

Answer:

The question can be rewritten as a quadratic equation, see the attachment to know how to solve it.

Answer 2

$\huge\color{cyan}\boxed{\colorbox{black}{\sf{ANSWER ❤}}}$

$5 {m}^{2} - 2m = 2$

$5 {m}^{2} - 2m - 2 = 0$

$using \: the \: quadratic \: formula :$

$m = \frac{ - b± \sqrt{ {b}^{2} - 4ac} }{2a}$

$a = 5$

$b = - 2$

$c = - 2$

$now$

$m = \frac{ - ( - 2)± \sqrt{ {( - 2)}^{2} - 4(5)( - 2)} }{2(5)}$

I solved in notebook and found that :

$m = \frac{1± \sqrt{11} }{5}$
