Does the polynomial a 4 + 4a 2 + 5 have real zeroes? fnd it asapjdshyycb Does the polynomial a4 + 4a2 + 5 have real zeroes?fnd it asapjdshyycb
Dear StudentIn the aforementioned polynomial, let a^2= x.Now, the polynomial becomes,x^2+ 4x+ 5Comparing with ax^2+ bx + c,Here, b^2– 4ac = 4^2– 4(1)(5)= 16 – 20= -4So, D = b2– 4ac < 0As the discriminant (D) is negative,the given polynomial does not have real roots or zeroes.Thanks
