Question

what is the quotient of x¹¹and x⁵ A.x b.x–⁶ C.x⁶ D.x¹⁶​

Answer 1

Answer:

Solution

f(x)=x

3

+ax

2

+bx+6

(x−2) in a factor ⇒f(2)=0

f(2)⇒2

3

+a(2)

2

+2b+6=0

⇒8+4a+2b+b=0

⇒4a+2b+14=0

⇒2a+b+7=0 -(1)

f(x−3)=3 (Remainder)

⇒f(3)⇒3

3

+a(3)

2

+b×3+6=3

⇒27+9a+3b+b=3

⇒9a+3b+30=0

⇒3a+b+10=0 _____ (2)

From (1) & (2)

b=−2a−7 & b=−10−3a

−2a−7=−10−3a

3a−2a=−10+7

a=−3

from (3)

b=−2(a)−7=2(−3)−7

=6−7

b=−1

Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests.
