Question

find the zero of the polynomial
(x-2)^2+4

Answer 1

Answer:

Concept:

The discriminant is the b2-4ac component of the quadratic formula beneath the square root sign. The discriminant indicates whether there are two, one, or no solutions available.

Step-by-step explanation:

Given:

(x-2)^2+4

Find:

zero of the polynomial
Solution:

$(x-2)^{2}+4 \\ =x^{2}+2^{2}-4 x+4 \\ =x^{2}-4 x+8 \\discriminant, \Delta=b^{2}-4 a c \\ =(-4)^{2}-4(1)(8) \\ =16-32 \\ =-16$

So it doesnt have any zero

Answer 2

Answer:

opening (x-2)²+4 using identity.

Then using middle term split to get the factors.

as the degree of the polynomial is 2 so the maximum number of factors is also 2.
