Question

a) Write the polynomial x²- 4 as the product of two first degree polynomial b) Find the number k, for x-1 to be a factor of the polynomial x²+kx-4​

Answer 1

Answer:

hope this helps you dear

Answer 2

Answer:

(a)x²-3x+2=x²-2x-x=x(x-2)+1(x-2)=(x+1)(x-2)

(b) Since x²-3x+ k can be written as the product of two degree

polynomials,

b² -4ac=0

(3)²-4(1)(k)=0➡️9-4k=0

k=9/4
