5. multiple choice what are all the rational
zeros of f(x) = – x2 – 17x – 157
a -3, - 1,5
b - 3, 1, 5
© -5, -1, 3
d – 5, 1, 3
e – 1, 3, 5

The answers are not correct

Step-by-step explanation:

For finding the rational zeros of this function, we need to resolve this equation:

multiplying by -1 on both sides

And now we can use the general solution of a cuadratic equation:

Where

a = 1

b = 17

c = 157

This equation does not have real solutions

Maybe you could verify if the function is written correctly

step-by-step explanation:

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
