Which is a third degree polynomial with -3 and 2 as its only zeros?

jek_recluse [69]

Answer:b

Step-by-step explanation:

f(x)=x^3+2x^2-5x-6

Put x= -3 in the equation

f(-3)=-3^3+2*3^2-5*3-6

= -27+18+15-6= 0

f(2)= 2^3+2*2^2-5*2-6

=8+8-10-6= 0

Write the equation line with a slope of -5 and a y intercept of 2.

Bond [772]

Answer:

y = -5x + 2

Step-by-step explanation:

Think about it this way:

y = ax + b

(a) = represents the slope

(b) = represents the y-intercept.

if the Y- intercept is negative so the "+" will turn to a "-"

In the expansion of ( x^3 - 2/x^2 ) ^10 , find the coefficient of 1/x^5

Lilit [14]

Answer:

240

Step-by-step explanation:

We need to find the coeffeicent of the binomial expansion of

$( {x}^{3} - 2 {x}^{ - 2} ) {}^{10}$

Note that

$- 2 {x}^{ - 2} = - \frac{2}{ {x}^{2} }$

The binomial theorem states that

$(x + y) {}^{n} = x {}^{n} y {}^{0} + \binom{n}{1} x {}^{n - 1} y + \binom{n}{2} x {}^{n - 2} y {}^{2} ....... + x {}^{0} y {}^{n} ( \binom{n}{n} )$

Using this, we let expand our series

$( {x}^{3} - 2 {x}^{ - 2} ) {}^{10} = x {}^{30} + \binom{10}{1} ( {x}^{27} 2 {x}^{ - 2} ) + \binom{10}{2} {x}^{24} 2x {}^{ - 4} + \binom{10}{3} {x}^{21} 2x {}^{ - 6} + \binom{10}{4} {x}^{18} 2x { }^{ - 8} + \binom{10}{5} x {}^{15} 2x {}^{ - 10} + \binom{10}{6} x {}^{12}2 x {}^{ - 12} + \binom{10}{7} x {}^{ 9} 2x {}^{ - 14} + \binom{10}{8} x {}^{ 6} 2x {}^{ - 16} + \binom{10}{9} ( {x}^{3} )2x {}^{ - 18} + 2x {}^{ - 20}$
