This is daniela's work to solve the equation 13x+42=276 13x+42=276 13x=318 x=24 6/13 which property does daniela need to use to avoid her error a)division property of equality b) multiplication property of equality tea c) subtraction property of equality d) identity property of equality

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.
