Can someone please help me with this problem I’m really struggling

1

Step-by-step explanation:

I am assuming the question is asking which x value plugged into the function will give you a zero so

(-1)3 -8(-1)2 -23(-1)+30

so that simplyfiys to -1-8(1)+23+30

so that is -1-8+53

so -9+53

= 44

trying 3 we get

(3)3-8(3)2-23(3)+30

so that is 27 -72-69+30

and that is not zero

trying -10

we get

(-10)3-8(-10)2-23(-10)+30

which is -1000- 800+230+30

that is not zero so lastly trying  1 we get

(1)3-8(1)2-23(1)+30

which is 1-8-23+30

which is -7+7 which is zero

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
