Why do math teachers not like the “FOIL” idea (as if it is the wrong way to think of the operations)? No answers needed just take the points.

Because its much more efficient if u do it in ur head

Step-by-step explanation:

thanks for points

cause they are racist towards foil

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.
