#1 Gigi's sister is 7 years less than twice Gigi's age, a. The sum of Gigi's
age and her sister's age is 41. Which equation represents this relationship?
O a + (7 - 2a) = 41
a + (2a - 7) = 41
2a - 7 = 41
O a = 2a - 7

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.
