How many roots of the polynomial 30x^4 + 7x^3-125x^2-54x+72 have absolute value greater than 1?

There are 3 roots of the given polynomial that have absolute value greater than 1.  

Step-by-step explanation:

We are given the polynomial:

We can factorize the given polynomial as:

Thus, there are 3 roots of the given polynomial that have absolute value greater than 1.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

16 is the absolute value
