Answer:

A perfect cube is a number that is the result of multiplying a whole number by itself three times. Check a number by finding the cube root. If the cube root is a whole number, then the number is a perfect cube.

Which value must be added to the expression x^2+12x to make it a perfect-square trinomial?
Studentka2010 [4]

Answer:

Add 36. The factored form is (x+6)^2.

Step-by-step explanation:

A perfect square is a trinomial that factors into the form (x+a)^2. To find the value to add to it divide 20 by 2 and square it.

12/2 = 6

6*6 = 36

This means c=36. The factored form is (x+6)^2.
