SIMPLIFY 1/4 × 1/3 - 1/5× 1/4 + 1/4 × 1/6

3/40

Step-by-step explanation:

1/4 x 1/3 - 1/5 x 1/4 +1/4 x 1/6

(1/4 x 1/3) - (1/5 x 1/4) + (1/4 x 1/6)

1/12 - 1/20 + 1/24

1/30 + 1/24

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.
