Given a polynomial f(x), if (x + 5) is a factor, what else must be true?f(0) = 5
f(0) = −5
f(5) = 0
f(−5) = 0

Answers

Answer 1

Answer:

f(0) = - 5 represents the correct value for the polynomial f(x).

What is a polynomial?

Polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s). Example -

5x³ + 4x + 5

Given is a polynomial f(x) and (x + 5) as its factor.

If (x + 5) is the factor, then the graph of f(x) cuts [x] axis at x = - 5. So,

f(0) = - 5.

Therefore, f(0) = - 5 represents the correct value for the polynomial f(x).

Answer 2

Answer: Rule: If x-k is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem.

Using that rule, we can see that x+5 is really x-(-5) so k = -5.

Therefore,

p(k) = 0
p(-5) = 0

so the answer is choice D.

Isolate c
a=b(1/c-1/d)

Answers

A= b(1/c - 1/d)
A/b = 1/c -1/d
A/b + 1/d = 1/c
(A/b + 1/d) 1 = c

Answer: c = b/(a + 1).

Step-by-step explanation:

a = b(1/c - 1/d)

Expand RHS by first finding LCM

a = b((d — c)/cd)

a = (bd — bc)/cd

Then cross multiply

acd = bd — cd

Collect the terms having c to the LHS

acd + cd = bd

Factorise cd out of LHS

( a+ 1)dc = bd

c = bd/(a + 1)d

c = b/(a + 1).
