Simplifying
5x + 4 = x + 44

Reorder the terms:
4 + 5x = x + 44

Reorder the terms:
4 + 5x = 44 + x

Solving
4 + 5x = 44 + x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1x' to each side of the equation.
4 + 5x + -1x = 44 + x + -1x

Combine like terms: 5x + -1x = 4x
4 + 4x = 44 + x + -1x

Combine like terms: x + -1x = 0
4 + 4x = 44 + 0
4 + 4x = 44

Add '-4' to each side of the equation.
4 + -4 + 4x = 44 + -4

Combine like terms: 4 + -4 = 0
0 + 4x = 44 + -4
4x = 44 + -4

Combine like terms: 44 + -4 = 40
4x = 40

Divide each side by '4'.
x = 10

Simplifying
x = 10

Which correctly describes the roots of the following cubic equation x^3-5x^2+3x+9=0? A. Three real roots, each with a different

77julia77 [94]

Answer:

The correct option is C.

Step-by-step explanation:

The given cubic equation is

$x^3-5x^2+3x+9=0$

According to the rational root theorem 1 and -1 are possible rational roots of all polynomial.

At x=-1, the value of function 0. Therefore (x+1) is the factor of polynomial and -1 is a real root.

Use synthetic division to find the remaining polynomial.

$(x+1)(x^2-6x+9)=0$

$(x+1)(x^2-2(3)x+3^2)=0$

Using $(a-b)^2=a^2-2ab+b^2$

$(x+1)(x-3)^2)=0$

USe zero product property and equate each factor equal to 0.

$x=-1,x=3,x=3$

Therefore the equation have three real roots out of which the value of two roots are same.

Option C is correct.
