Which shows a perfect square trinomial? a 50 y squared minus 4 x squared b 100 minus 36 x squared y squared c 16 x squared + 24 x y + 9 y squared d 49 x squared minus 70 x y + 10 y squared

OPTION C

Step-by-step explanation:

For this problem it is important to remember that a trinomial is a polynomial with three terms and a binomial is a polynomial with two terms.

By definition, when you square a binomial, you get a perfect square trinomial:

Observe the trinomial given in Option C:

You can identify that:

Therefore, you can conclude that   is a perfect square trinomial.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

f(x)=4
