Question

check whether x=-1/2 is a solution for the equation 2x^2-5x-3=0​

Answer 1

Step-by-step explanation:

2x^2-5x-3=0

2x^2-6x+x-3=0

(x-3)(2x+1)=0

x=3 and x=-1/2

Answer 2

Answer:

No

Step-by-step explanation:

QUESTION:-

Check whether x = -½ is a solution of the equation 2x²-5x - 3 = 0

ANSWER:-

If x = -½ is the solution of this equation, then on solving we should get zero as remainder.

Put the value of x in the equation.

2x²-5x-3 = 0

2(-½)² - 5(½) - 3 = 0

½ - ⁵/2 - 3 = 0

-⁴/2 - 3 = 0

L. C. M = 2

(-4 -6)/2 = 0

-10/2 = 0

-5 ≠ 0

So , here the remainder ≠ 0. So x = -½ is not the solution of the equation.
