Answer:

A) x = -8

B) x = 3

Step-by-step explanation:

This quadratic is already factored so all we have to do is solve for the zeroes. We can separate the two factors of the quadratic into x-3=0 and x+8=0. Solve for x in both of the equations and we get the zeroes as x = 3 and x = -8.

Answer:

3 and -8 are the zeroes of polynomial.

Option A and D are correct.

Step-by-step explanation:

Given the polynomial

[tex]f(x)=(x-3)(x+8)[/tex]

we have to find the zeroes of the above polynomial.

Zeroes of polynomial are those values which makes the value of polynomial 0 when substituted.

to find the zeroes we have to substitute the polynomial equals to 0

[tex]f(x)=(x-3)(x+8)=0[/tex]

which implies

[tex]x-3=0, x+8=0[/tex]

[tex]x=3, x=-8[/tex]

Hence, 3 and -8 are the zeroes of polynomial.

Option A and D are correct.
