Question

the zero of polynomial p(x)= x²-5x+4 is​

Answer 1

Step-by-step explanation:

by split middle term

x²-4x-1x+4

x(x-4) -1(x-4)

(x-4) (x-1) = 0

x = 4,1

Answer 2

Answer:

Zeroes of polynomial x

2

+5x−204

Using common factor method

x

2

+17x−12x−204

=x(x+17)−12(x+17)

=(x−12)(x+17)

To find zeroes of polynomial, we can equate the factor equal to zero.

∴(x−12)=0 ; (x+17)=0

x=12 ; x=−17

(12,−17) zeroes of polynomial.

Hence, the answer is (12,−17).
