Find all the zeros of the equation. -x^3-3x^2=6x+4

The zeros of given expression is -1, and

Step-by-step explanation:

Given expresssion is

To find zeros of given expression we have to equate the expression to zero.

ie.,

By using synthetic division

-1  |  1    3    6    4

    |  0   -1   -2   -4

    |________________

       1    2   4    0

Therefore (x+1) is a  zero

Now the quadratic equation is

For quadratic equation  we have

Here a=1 ,b=2 and c=4 now substitute the values

where

Therefore  and

Therefore the zeros are -1, and

rx and sx

step-by-step explanation:

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
