Find an upper limit for the zeroes 2x^4 -7x^3 + 4x^2 + 7x - 6 = 0

erik [133]

Answer-

2 is the upper limit for the zeros.

Solution-

The given function f(x) is,

$2x^4 -7x^3 + 4x^2 + 7x - 6 = 0$

For calculating the zeros,

$\Rightarrow f(x)=0$

$\Rightarrow 2x^4 -7x^3 + 4x^2 + 7x - 6 = 0$

$\Rightarrow 2x^4-4x^3-3x^3+6x^2-2x^2+ 4x+3x-6=0$

$\Rightarrow 2x^3(x-2)-3x^2(x-2)-2x(x-2)+3(x-2)=0$

$\Rightarrow (x-2)(2x^3-3x^2-2x+3)=0$

$\Rightarrow (x-2)(x^2(2x-3)-1(2x-3))=0$

$\Rightarrow (x-2)(x^2-1)(2x-3)=0$

$\Rightarrow (x-2)(x+1)(x-1)(2x-3)=0$

$\Rightarrow x-2=0,\ x+1=0,\ x-1=0,\ 2x-3=0$

$\Rightarrow x=2,\ x=-1,\ x=1,\ x=\frac{3}{2}$

From all the 4 roots, it can be obtained that 2 is the greatest zero.

You have 3/4 of a pie leftover after your party. Each guest takes home 1/6 of the leftover pie.

Anika [276]

we know that

1) You have $3/4$ of a pie leftover after your party

2) Each

guest takes home $1/6$ of the leftover pie

To find the fraction of the original pie does each guest take home,

Multiply $3/4$ by $1/6$

$\frac{3}{4} *\frac{1}{6} =\frac{3}{24}$

Simplify

Divide by $3$ both numerator and denominator

$\frac{3}{24}=\frac{1}{8}$

therefore

the answer is

$\frac{1}{8}$
