Programming cannot be done without mathematics logic. I want to solve (a+b)^{2} in the PHP programming language. I am a beginner in PHP. I won't use the mathematics formula (a+b)^{2} in the PHP language. How can convert the mathematics formula (a+b)^{2} in PHP? It is a famous mathematical formula.

PHP programming is based on operators and operands. If you are already learned operators in the C language, you will understand easily. You can use mathematics formula (a+b)^{2 } in the PHP language. First of all, you need to learn about PHP data types.

Think about the variables in mathematics formula (a+b)^{2} There is two variable in this formula a and b.

How to open the mathematics formula (a+b)^{2 }–

`(a+b)2=a2+b2+2ab`

How can write the line mathematics line a^{2}+b^{2}+2ab

`a2+b2+2ab=a*a+b*b+2*a*b`

if a=2 and b=4

then,

```
a2+b2+2ab=2*2+4*4+2*2*4
= 4+16+16
=36
```

You can use this mathematics logic in PHP programming

Asterisk sign (*) is used for multiplication in computer programming languages.

We declare the variables in PHP like this –

```
$a;
$b;
```

Use the above mathematics login –

`a*a+b*b+2*a*b`

Let’s create a program for mathematics formula (a+b)^{2 }in PHP language –

```
<?php
$a=5;
$b=6;
echo "(a+b)<sup>2</sup>=a<sup>2</sup>+b<sup>2</sup>+2ab";
$result=($a*$a+$b*$b+2*$a*$b);
echo "=".$result;
?>
```

You will get the result as output –

`(a+b)2=a2+b2+2ab=36`

You can change variables (a,b) values according to your needs.
