We have the identity -a-b-2-a2-2ab-b2Here a-3x-b-5By using this identity- we can solve further as-xA0-3x-5-2-3x-2-52-2-xD7-3x-xD7-5-9x2-25-30xThis is the required answer-

Find out the following squares by using the identities:
$(3 x + 5)^{2}$

We have the identity $(a + b)^{2} = a^{2} + 2 a b + b^{2}$
Here $a = 3 x, b = 5$
By using this identity, we can solve further as
$(3 x + 5)^{2} = (3 x)^{2} + 5^{2} + 2 \times 3 x \times 5 = 9 x^{2} + 25 + 30 x$
This is the required answer.

Find out the following squares by using the identities:(3x+5)2

We have the identity (a+b)2=a2+2ab+b2Here a=3x,b=5By using this identity, we can solve further as (3x+5)2=(3x)2+52+2×3x×5=9x2+25+30xThis is the required answer.
