Sagot :

Mizuviz
1) Square the 1st term.
2) Multiply the 1st term and 2nd term.
3) Square the 2nd term.
Examples: 
[tex](x+3)^2 \\ (x+3) (x+3) \\ =x^2+ 6x + 9[/tex]

[tex](2x +3)^{2} + 5 \\ (2x +3) (2x+ 3) +5 \\ 4x^2 + 12x+ 9+ 5 \\ = 4x^{2} + 12x+ 14[/tex]

1. Square the first term.
2. Multiply the two terms together and double.
3. Square the last term.

Note: The first and last terms will always be positive. The middle term will have the same sign as the original binomial.
