What is the value of x in the equation x+4/9=3/4

Step-by-step explanation:

Subtract with 4/9 on both sides and we get:

To get the same value we multiply 3/4 with 9, and 4/9 with 4. Then we have:

And at last we get that x = 11/36

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.

correct answer:

b.(19,-2)
