P(x) = x^4+ax^3-x^2+bx-12 has factors of (x-2) and (x+1). Solve the equation P(x)=0

Feliz [49]

Answer:

because P(x) has factors of (x-2) and (x+1) => x = 2 and x = -1 are the solutions of P(x)

so we have:

$\left \{ {{2^{4}+2^{3}a-2^{2}+2b-12 =0} \atop {1-a-1-b-12=0}} \right.\\=>\left \{ {{8a+2b=0} \atop {a+b=-12}} \right.\\\left \{ {{4a+b=0} \atop {a+b=-12}} \right.\\\left \{ {{a=4} \atop {b=-16}} \right.$

=> $P(x)=x^{4} + 4x^{3}-x^{2} -16x-12$

With P(x) = 0

=> $x^{4}+4x^{3}-x^{2} -16x-12 = 0$

=> ........

Explain why it would not make sense to approximate 256 using the binomial theorem for the binomial (20 + 5)6.

Olenka [21]

The formula for the Binomial Theorem with a power 6 is as:

$(x+y)^6=x^6+6x^5y+15x^4y^2+20x^3y^3+15x^2y^4+6xy^5+y^6$

Thus, if we plug in 20 for x and 5 for y, our first term itself will be $20^6=64000000$ which is much greater than 256 and thus it will not make any sense to use $(20+5)^6$ to approximate 256 using the binomial theorem.

Also, it will not make any sense to use $(20+5)6$ as that has no power and we know that Binomial Theorem makes use of Power. Anyway, $(20+5)6=150\neq 256$ .
