When dividing polynomials using factorization, canceling identical factors in the denominator and the numerator will give the .

quotient

Step-by-step explanation:

Cancelling identical factors in the numerator and the denominator will give the quotient. For example,x2+5x+6x+3=(x+2)(x+3)x+3 = x + 3

Option C: $30 is the original price of book.

Step-by-step explanation:

Let the original price of book be x

Given that:

Sale price = x - 40% of x

As it is given that the sale price was $18

So,

$18 =  x - 40% of x

By simplifying:

$18 = x - 0.4x

$18 = 0.6x

Dividing both sides by 0.6:

x = $18/0.6

x = $ 30

So the original price of book will be $30
