Answer:
Step-by-step explanation:
Given the quadratic expression x^2-2x-24, to get the values of the variable for which the expression is defined as a real number, we need to factorize the expression first as shown;
= √x^2-2x-24 = 0
= √x^2-6x+4x-24= 0
=√x(x-6)+4(x-6) = 0
=√(x+4)(x-6) =0
square both sides
= (x+4)(x-6) = 0²
(x+4)(x-6) = 0
(x+4) = 0 and (x-6) = 0
x = -4 and x = 6
Hence the interval of notation is at x = -4 and 6

Given that,

and

<em>We know, </em>
Factor theorem states that if g(x) = x - a is a factor of polynomial f(x), then remainder f(a) = 0.
So, using Factor theorem, Consider







<u>So, </u>



and

Now, By using Factor Theorem, Consider





<u>So, </u>

The correct answer is, B. (–1, 0)
Answer:
C
Step-by-step explanation:
ok so sam started with 0 and got -9 then he got 12 then the next known number is -8 so those three numbers together are -5 and the end result was -1 so -1 minus -5 is -4 therefore the anser is C
