6 0

Answer: 5 and 6

Step-by-step explanation:

X^2 - 11 = (X-1)^2

X^2 - 11 = X^2-2X+1

X^2 - X^2 + 2X = 11+1

2X = 12

X = 6

The preceding number is 5

(6)(6)=36 and (5)(5)=25

36-25=11

Evaluate the polynomial for the given value of x: f(x) =3x^3+5x^2+x-2 when x=2

sasho [114]

Answer: $f(2)=44$

Step-by-step explanation:

Given the polynomial $f(x) =3x^3+5x^2+x-2$ , you can evaluate it for the given value of the variable "x" by substituting the value $x=2$ into the polynomial.

Therefore, when $x=2$ , you get the following result:

$f(x) =3x^3+5x^2+x-2 \\\\f(2) =3(2)^3+5(2)^2+(2)-2\\\\f(2)=3(8)+5(4)+2-2\\\\f(2)=24+20\\\\f(2)=44$
