(i) x2 + 6x – 4 = 0
Solution:
Let p(x) = x2 + 6x – 4,
It’s clearly seen that p(x) = x2 + 6x – 4 is a quadratic polynomial. Thus, the given equation is a quadratic equation.
(ii) √3x2 – 2x + 1/2 = 0
Solution:
Let p(x) = √3x2 – 2x + 1/2,
It’s clearly seen that p(x) = √3x2 – 2x + 1/2 having real coefficients is a quadratic polynomial. Thus, the given equation is a quadratic equation.
