What is 3/4 - 1/5 written in the simplest form

11 / 20

Step-by-step explanation:

3/4 - 1/5

You cannot perform this if you have two different denominator.

So multiply both pairs with each other's denominator.

3 × 5 = 15        1 × 4 = 4

4 × 5 = 20       5 × 4 = 20

Now we can perform subtraction.

15/20 - 4/20

15 - 4 = 11

11 / 20

Find common denominators.

3/4 = 15/20

1/5 = 4/20

Subtract.

15/20 - 4/20 = 11/20

11/20 cannot be simplified any further.

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.
