Question

if one root of equation 2x2+3x-2= 0 os 1\2 then other root is plz explain step by step answer​

Answer 1

Answer:

Other Root of the given equation is x = -2 ..

Answer 2

Answer:

-2

Step-by-step explanation:

$2 {x}^{2} + 3x - 2 = 0$

Here,

a = 2

b = 3

c = -2

For any quadratic polynomial,

sum of its roots = $\frac{ - b}{a}$

$\frac{1}{2} + x = \frac{ - 3}{2}$

$x = \frac{ - 3}{2} - \frac{1}{2}$

$x = \frac{ - 4}{2}$

$x = - 2$

verification :

2x$^2$ + 3x - 2 = 0

2(-2)$^2$ + 3(-2) - 2 = 0

8 - 6 - 2 = 0

8 - 8 = 0
