## Which number is added to perfect square x2 16x?

We have to add 82 64, to convert it into a perfect square. Therefore, 64 must be added to the expression to make it a perfect-square trinomial.

## Can you factor x2 16?

There are two ways to factorize x2u221216 – one using identity a2u2212b2(a+b)(au2212b) . Other method is by splitting the middle term, which is 0 here and as product of coefficient of x2 and constant term is u221216 . we need to do is to split middle term in 4 and u22124 (as their sum is zero and product is u221216 ).

## What is x2 9 Factorised?

To complete the square, you take the square root of the number in the question. Remember that there will be a positive and a negative square root, so here the roots of 9 will be 3 and -3. Then you can factorise the expression like so:x2-9(x+3)(x-3)Notice how each bracket contains an x and one of the square roots?

## Which is the perfect square trinomial?

A perfect square trinomial is a trinomial that can be written as the square of a binomial. Recall that when a binomial is squared, the result is the square of the first term added to twice the product of the two terms and the square of the last term. We can use this equation to factor any perfect square trinomial.
