Answer 2

Question :

•The quadratic equation is :

✒ 2m²+7m-5=0

To find :

•The roots of given quadratic equation =?

Given equation :

• 2m²+7m-5

Solution :

➡

$\\ \implies \large \sf \: 2 {m}^{2} + 7m - 5 = 0$

$\\ \implies \large \sf \: 2 {m}^{2} + 5m + 2m - 5 = 0$

$\\ \implies \large \sf \: m(2m + 5) - 2(2m + 5)$

$\\ \implies \large \sf \: (m - 2)(2m + 5) = 0$

$\\ \implies \large \sf \: \boxed{m = 2 }\: \: \: and \: \: \boxed{m = \frac{ - 5}{2} }$

Roots of the equation are m=2 and m=-5/2
