Question

check whether the following are quadratic equations; √3x^2- 2x + 3 /5= 0
​

Answer 1

Yes they are quadratic equation as they satisfy the standard form of quadratic equation i.e ax^2 + bx + c

Answer 2

hello friends ,

discriminant = b^2 - 4ac

equation = under root 3x^2 - 2x +3/5

a = under root 3

b = -2

c = 3/5

now , D = (root 3 ) ^2 - 4(-2)(3/5 )

           = 3 + 24 /5

           = 39/5 = 7.8

since, discriminant is greater than 1

hence , it is a quadratic polynomial

having two unequal roots
