Pls help i really need it asap

Blank 1 = -1

Blank 2 = 2

Blank 3 = 4

Blank 4 = 7

Blank 5 = 79

Step-by-step explanation:

Blank 1 has an input of 1 we have to square 1

1 squared = 1

Then we subtract 2

1 - 2 = -1

Blank 2 has an input of 2 we have to square 2

2 squared = 4

Then subtract 2

4 - 2 = 2

Blank 3 has an output so we have to do the opposite of what we would for an input

Blank 3 has an output of 14 so we add 2

14 + 2 = 16

then we have to do the square root

The Square root of 16 = 4

So the input was 4

Blank 4 has an output of 47

47 + 2 = 49

The square root of 49 = 7

So the input was 7

Blank 5 has an input of 9

9 squared = 81

81 - 2 = 79

So the output is 79

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
