# Is the number 1600 a perfect square?

## Is the number 1600 a perfect square?

1600 is a number that is a perfect square which means that it has a natural number as its square root. Square root of 1600 is 40.

### How do you find the perfect square trinomial?

Any time you take a binomial and multiply it to itself, you end up with a perfect square trinomial. For example, take the binomial (x + 2) and multiply it by itself (x + 2). The result is a perfect square trinomial.

**What is an example of a perfect trinomial?**

4x 2 + 12x + 9 is a perfect square trinomial. 4x 2 + 12x + 9 = (2x) 2 + 2(2x)(3) + (3) 2 Write as a2 + 2ab + b2 .

**What makes a perfect square?**

A perfect square is a number that can be expressed as the product of two equal integers. For example, 25 is a perfect square because it is the product of two equal integers, 5 × 5 = 25. However, 21 is not a perfect square because it cannot be expressed as the product of two equal integers. (7 × 3 = 21).

## Is 8 a perfect square?

Perfect Squares and Perfect Cubes For example x8 is a perfect square, its square root is x4 . x11 is not a perfect square.

### Is x2 10x 25 a perfect square trinomial?

Yes, x2+10x+25 is a perfect square trinomial.

**How do you determine a perfect square?**

You can also tell if a number is a perfect square by finding its square roots. Finding the square root is the inverse (opposite) of squaring a number. If you find the square root of a number and it’s a whole integer, that tells you that the number is a perfect square.

**Which is an example of a perfect square trinomial?**

An expression is said to a perfect square trinomial if it takes the form ax 2 + bx + c and satisfies the condition b 2 = 4ac. The perfect square formula takes the following forms: (ax) 2 + 2abx + b 2 = (ax + b) 2. (ax) 2 −2abx + b 2 = (ax−b) 2. Example 1. Factor x 2 + 6x + 9. Solution.

## How to see the pattern in a trinomial?

The trick to seeing this pattern is really quite simple: If the first and third terms are squares, figure out what they’re squares of. Multiply those things, multiply that product by 2, and then compare your result with the original quadratic’s middle term.

### Is it possible to make a square trinomial with binomials?

You should be able to take the binomials and find the perfect square trinomial and you should be able to take the perfect square trinomials and create the binomials from which it came. Any time you take a binomial and multiply it to itself, you end up with a perfect square trinomial.

**Which is the middle term in a trinomial?**

The first term, 4×2, is the square of 2x, and the last term, 36, is the square of 6 (or, in this case, –6, if this is a perfect square). According to the pattern for perfect-square trinomials, the middle term must be:
