Question

Determine the nature of the roots of the Following Quadratic equations.

2x^2 + x - 1 = 0​

Answer 1

Step-by-step explanation:

given equation,2x^2+x-1

multiply the first and last terms of the equation

that is 2x^2(-1)

=-2x^2

find the factors of 2x^2

2x^2-x+2x-1

take x has common here

x(2x-1)1(2x-1)

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

x=1;x=1/2
