Iwill give 99 points aida applied the distributive property to write the equivalent expressions below. 15 + 21 = 3(4 + 8) what is aida’s error? aida used 3 as the factor, which is not common to 15 and 21. aida did not correctly divide by the common factor to get (4 + 8). aida did not apply the correct operations to the expressions. aida wrote two expressions that are not equivalent.

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.
