Question

2x2 + x- 10 = 0 help me to solve this equation

Answer 1

Answer:

2x2+x-10=0

=> 4+x =10

=> x= 10 - 4

= > x= 6

Answer 2

${\texttt{\huge{\purple{SOLUTION :-}}}}$

$2 {x}^{2} + x - 10 = 0$

$2 {x}^{2} + (5 - 4)x - 10 = 0$

$2 {x}^{2} - 4x + 5x - 10 = 0$

$2x(x - 2) + 5(x - 2) = 0$

$(x - 2)(2x + 5) = 0$

First solution....

x = 2

Second solution....

$\underline{x = - \frac{5}{2} }$
