## How do you solve Trinomials step by step?

Formula For Factoring Trinomials (when a=1 )

- Identify a, b, and c in the trinomial ax2+bx+c.
- Write down all factor pairs of c.
- Identify which factor pair from the previous step sum up to b.
- Substitute factor pairs into two binomials.

## Is 4 a perfect square?

For instance, the product of a number 2 by itself is 4. In this case, 4 is termed as a perfect square. A square of a number is denoted as n × n. Example 1.

Integer | Perfect square |
---|---|

2 x 2 | 4 |

3 x 3 | 9 |

4 x 4 | 16 |

5 x 5 | 25 |

## Is 20 a perfect square?

A: No, the number 20 is not a perfect square.

## Is 25 a perfect square?

Since 25 is a natural number and the square root of 25 is a natural number (5), 25 is a perfect square. 24 is a natural number, but since there is no other natural number that can be squared to result in the number 24, 24 is NOT a perfect square.

## Is 16 a perfect square?

## Is 12 a perfect square?

A: No, the number 12 is not a perfect square.
