Based on the lesson, identify the first operation needed to solve the equation. 11x + 3 = 3 addition subtraction multiplication division

To get the variable by itself on one side of the equation and a number on the other side of the equation is our objective in solving the given equation.

We must reverse the operations acting on the variable to separate the variable. By performing the inverse of each operation on both sides of the equation, we can do it. The validity of the equation, or the value of the variable that satisfies it doesn’t change by performing the same operation on both sides of an equation.

11x + 3 = 3

11x = 3 – 3

11x = 0

11(0) = 0

As you can see, the first operation we did on the equation is subtract 3 from 3.

Therefore, the first operation needed to solve the equation 11x + 3 = 3 based on the lesson is subtraction.

step-by-step explanation:

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.
