How many unique triangles can be formed with side lengths of 9 units and 6 units, and an angle of 40 degrees NOT formed by the intersection of the two sides? (not between them) Your A. 0 B. 1 C. More than 1

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.

a - base

b - exponent

so,

the answer is d
