Question

find the product of the following using suitable identities. (i)(x+3)²,(ii) (2x+3y)² (iii) (2x²y+3xy²)² (iv) (x/2+1)². u can leave a problem if u dont know but can any one please answer some of these if u know please!..​

Answer 1

Step-by-step explanation:I'm just doing one mate and I hope you can do others by copying the formula

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

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

Answer 2

Answer:

I will do the 2nd problem.. Hope u can do other problems just by applying the same formula

Step-by-step explanation:

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

Here, a=2x , b=3y

(2x+3y) ^2= (2x) ^2+2(2x) (3y) +(3y) ^2

=4x^2+12xy+9y^2
