Given the following perfect square trinomial, find the missing term: ___x2 + 40x + 100 1 2 4 10

4

Step-by-step explanation:

The correct option is 4.

Put 4 in the missing term because 4 is a perfect square and it satisfies the given expression:

4x2 + 40x + 100

Now multiply the 1st term coefficient with 100

4 * 100 = 400

Now find two numbers whose product is 400 and whose sum is 40

20*20 = 400

20+20 = 40

Therefore 4 is the correct missing coefficient because it satisfies the expression:

Thus the correct option is 4 ...

4
