Question

Find zeroes of the following quadratic polynomials and verify the relationships between zeroes
and coefficients of the polynomials:
(a) p(x) = 8x2 - 19x - 15;
(b)q(x) = 4√3x2 + 5x -2√3.​

Answer 1

Step-by-step explanation:

Solution :

P(u)=4u2+8uP(u)=4u2+8u

P(u)=u(4u+8)P(u)=u(4u+8)

P(u)=0, when u=0

4u+8=0

u=-8/4=-2
