By using multiplication, [tex](2x+3)^{2}[/tex] = [tex]4x^{2} +12x+9[/tex].
What is multiplication?
Multiplication is the method of finding the product of two or more numbers. It is a primary arithmetic operation that is used quite often in real life. Multiplication is used when we need to combine groups of equal sizes.
Given
[tex](2x+3)^{2}[/tex]
= (2x + 3)(2x + 3)
= 2x (2x) + 2x(3) + 3(2x) +3(3)
= [tex]4x^{2} +6x+6x+9[/tex]
= [tex]4x^{2} +12x+9[/tex]
Hence, by using multiplication, [tex](2x+3)^{2}[/tex] = [tex]4x^{2} +12x+9[/tex].
