Question

find the value of x3^3x+3= 9x+4​

Answer 1

Step-by-step explanation:

Step by step solution :

STEP1:Equation at the end of step 1

(3x3 - 9x) - 4 = 0

STEP2:

Polynomial Roots Calculator :

 2.1    Find roots (zeroes) of :       F(x) = 3x3-9x-4

Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which   F(x)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  3  and the Trailing Constant is  -4.

 The factor(s) are:

of the Leading Coefficient :  1,3

 of the Trailing Constant :  1 ,2 ,4

 Let us test ....

Equation at the end of step2:

3x3 - 9x - 4 = 0

STEP3:

Cubic Equations:

 3.1     Solve   3x3-9x-4 = 0

Future releases of Tiger-Algebra will solve equations of the third degree directly.

Answer 2

Answer:

$x3 ^{3x} + 3 = 9x + 4 \\ x3 ^{3x} - 9x = 4 - 3 \\ x3 ^{3x} - 9x = 1$
