Solution

The image you uploaded is about completing a perfect square trinomial. Jeremiah is creating perfect square trinomials, and you are asked to move the correct term to complete each one.

A perfect square trinomial is of the form: a22ab+b2=(ab)2a^2 - 2ab + b^2 = (a - b)^2 or a2+2ab+b2=(a+b)2a^2 + 2ab + b^2 = (a + b)^2

Looking at the expressions given:

  1. x24x+ x^2 - 4x + \underline{\ }
  2. x2+20x+ x^2 + 20x + \underline{\ }
  3. x214x+ x^2 - 14x + \underline{\ }

Let’s figure out the terms needed to complete the perfect square trinomial:

  1. For x24xx^2 - 4x: The coefficient of xx is 4-4. To make a perfect square, we take half of 4-4, which is 2-2, and then square it to get 44. So the missing term is 4.

  2. For x2+20xx^2 + 20x: The coefficient of xx is 2020. Half of 2020 is 1010, and squaring it gives 100100. So the missing term is 100.

  3. For x214xx^2 - 14x: The coefficient of xx is 14-14. Half of 14-14 is 7-7, and squaring it gives 4949. So the missing term is 49.

Thus, the correct terms are:

  • x24x+4x^2 - 4x + 4
  • x2+20x+100x^2 + 20x + 100
  • x214x+49x^2 - 14x + 49
