The sign of the product of –35 and –625 is (positive, negative, zero)
The sign of the product of 263 and 0 is (positive, negative, zero)
The sign of the product of –21 and 451 is (positive, negative, zero)
The sign of the product of –350 and 89 is (positive, negative, zero)

Step-by-step explanation:

-35 x - 625 = 21875 so positive

263 x 0 = 0 so zero

-21 x 451 = - 9471 so negative

-350 x 89 = - 31150 so negative

step-by-step explanation:

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.
