Question

f(x) = 3x4 + 17x3 + 9x2 − 7x − 10, g(x) = x + 5​

Answer 1

Answer:

According to the problem:-

Given that:

f(x)=3x

4

+17x

3

+9x

2

−7x−10

and

g(x)=x+5

Using the factor theorem, g(x) is a factor of polynomial f(x)

Therefore,

x+5=0

x=−5

Hence,

f(−5)=3(−5)

4

+17(−5)

3

+9(−5)

2

−7(5)−10

Implies that

=3×625+17×(−125)+225+35−10

Implies that

=1875−2125+250

=0

Hence the g(x) is the factor of polynomial f(x)

Answer 2

Step-by-step explanation:

Ferrous sulfate (or sulphate) is a medicine used to treat and prevent iron deficiency anaemia. Iron helps the body to make healthy red blood cells, which carry oxygen around the body. Some things such as blood loss, pregnancy or too little iron in your diet can make your iron supply drop too low, leading to anaemia.
