Answer 1

Step-by-step explanation:

Q1)1)(6x-2y)(6x+2y)(36x²+4y²)

=[(6x)²-(2y)²](36x²+4y²)

=(36x²-4y²)(36x²+4y²)

=(36x²)²-(4y²)²

=1296x^4-16y^4

2)(w+y+b)(w+y-b)

=(w+y)²-(b)²

=w²+2wy+y²-b²

=w²+y²-b²+2wy

Q2)1)a+b=5

Squaring on both the sides

(a+b)²=(5)²

a²+b²+2ab=25

a²+b²+2(3)=25

a²+b²+6=25

a²+b²=25-6

a²+b²=19
