Question

(x+3)(x+3) solve using suitable identity

Answer 1

(x+3)(x+3)

(x+3)^2

(a+b)^2=a^2+b^2+2ab

(x+3)^2=x^2+9+6x

hope it helps

Answer 2

Answer:

The required value $(x+3)(x+3)=x^{2}+6x+9$

Step-by-step explanation:

In accordance with the information provided in the question,

Given the data in question (x+3)(x+3)

We have to use the identity (a+b)(a+b)

We can write this (a+b)(c+d)

Multiplying a into c with a into d and multiplying b into c with b into d

then get $ac+ad+bc+bd$

We get,

[tex](x+3)(x+3)=(x\times x)+(x\times 3)+(3\times x)+(3\times 3)\\ x^{2} +3x+3x+9\\ x^{2} +6x+9[/tex]

Hence the required value $(x+3)(x+3)=x^{2}+6x+9$
