Answer:

x = 3

x = 2

 x= ± √ -1

Step-by-step explanation:

 ((((x^4)-(5•(x^3)))+7x^2)-5x)+6  = 0

 ((((x^4) -  5x^3) +  7x^2) -  5x) +  6  = 0

Dividing :  x^4-5x^3+7x^2-5x+6  

                             ("Dividend")

By         :    x-3    ("Divisor")

Quotient :  x^3-2x^2+x-2  Remainder:  0

Dividing :  x^3-2x^2+x-2  

                             ("Dividend")

By         :    x-2    ("Divisor")

Quotient :  x^2+1  Remainder:  0

(x^2 + 1) • (x - 2) • (x - 3)  = 0

x^2+1 = 0

x^2 = -1

x  =  ± √ -1

x-2 = 0

x = 2

x-3 = 0

x = 3

Find the limit of the function algebraically. limit as x approaches negative nine of quantity x squared minus eighty one divided
scoray [572]
Let me express the equation clearly:

lim x→-9  (x²-81)/(x+9)

Initially, we solve this by substituting x=-9 to the equation. 

((-9)²-81)/(-9+9) = 0/0

The term 0/0 is undefined. This means that the solution is not see on the number line because it is imaginary. Other undefined terms are N/0 (where N is any number), 0⁰, 0×∞, ∞-∞, 1^∞ and ∞/∞. One way to solve this is by applying L'Hopitals Rule. This can be done by differentiating the numerator and denominator of the fraction independently. Then, you can already substitute the x=-9.

(2x-0)/(1+0) = 2x = 2(-9) = -18

The other easy way is to substitute x=-8.999 to the original equation. Note that the term x→-9 means that x only approaches to -9. Thus, you substitute a number that is very close to -9. Substituting x=-8.999

((-8.999)²-81)/(-8.999+9) = -18
