Why is (12-23) • 2 not the same as 12-(3•2)

Step-by-step explanation:

Note the system of equation, PEMDAS. First, you solve parenthesis, then multiplication, then subtraction.

In this case, solve each of the expression given to us. Remember that parenthesis is first:

(12 - 23) * 2 = (-11) * 2 = - 22

12 - (3 * 2) = 12 - (6) = 6

- 22 ≠ 6

~

It's not the same because According to PEMDAS

P⇒ Parentheses

E⇒ Exponets

M⇒ Multiplication

D⇒ Division

A⇒ Addition

S⇒ Subtraction

Parentheses goes first and those 2 problems are two different things. Also, this also shows inequality in another words:))

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.
