over

x2 - x1

Inputting the numbers, 6 - -7 (aka 6+7) over -3 - -7 (aka -3+7)

6+7 = 13

-3+7 = 4

13/4 - The line is rising moving towards the right.

What value in place of the question mark makes the polynomial below a perfect square trinomial ?

gregori [183]

Answer:

Option D is correct.

Step-by-step explanation:

We have been given $x^2+22x+?$

We need to tell which one of them will give the perfect square trinomial.

Trinomial is the polynomial with three terms.

$x^2+22x+121$

If we factorize it by middle term splitting we get:

$x^2+11x+11x+121$

$\Rightarrow x(x+11)+11(x+11)$

$\Rightarrow (x+11)(x+11)$

$\Rightarrow (x+11)^2$ is the perfect square trinomial.

Therefore, option D is correct
