Question

3x⁴+17x³+9x²-7x-10 by x+5 by long division method.​

Answer 1

Answer:

According to the problem:-

Given that:

f(x)=3x 4 +17x 3 +9x 2 −7x−10andg(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)
