108

Explanation:

a+b=4

ab=3

(ab)³*(a+b)=27*4=108

Answer:

189

Explanation:

Hello dear friend,

For a quadratic polynomial [tex]\( f(t) = at^2 + bt + c \)[/tex], with zeros [tex]\( \alpha \)[/tex] and [tex]\( \beta \)[/tex], the sum of the zeros is given by [tex]\( \alpha +\beta = -\frac{b}{a} \)[/tex], and the product of the zeros is given by [tex]\( \alpha \beta = \frac{c}{a} \)[/tex].

From Vieta's formulas:

  • Sum of the zeros: [tex]\( \alpha + \beta = -(-4) = 4 \)[/tex]
  • Product of the zeros: [tex]\( \alpha \beta = 3 \)[/tex]

Now, we need to find [tex]\( \alpha^4 \beta^3 + \alpha^3 \beta^4 \)[/tex].

We can rewrite [tex]\( \alpha^4 \beta^3 + \alpha^3 \beta^4 \) as \( \alpha^3 \beta^3 (\alpha + \beta) + \alpha^3 \beta^3 (\alpha \beta) \)[/tex].

Substituting the known values:

[tex]\( = 3^3 \cdot 4 + 3^3 \cdot 3 \)[/tex]

Calculating:

[tex]\( = 27 \cdot 4 + 27 \cdot 3 \)[/tex]

[tex]\( = 108 + 81 \)[/tex]

[tex]\( = 189 \)[/tex]

So, the value of [tex]\( \alpha^4 \beta^3 + \alpha^3 \beta^4 \)[/tex] is 189.

Do let me know if there are any mistakes as I'm only human. Every human makes mistakes, it's okay :p

I hope you have understood my explanation and felt it was somewhat helpful to you.

Have a great day ahead !
