Answer 2

Step-by-step explanation:

1)Given that:-

(6y-7z)²

this is in the form of (a-b)²

Here a=6y and b=7z

we know that

(a-b)²=a²-2ab+b²

(6y-7z)²=(6y)²-2(6y)7z)+(7z)²

(6y-7z)²=36y²-84yz+49z²

2) given that

(2+2+6p)²

=>(4+6p)²

This is in the form of (a+b)²

here a =4 and b=6p

we know that

(a+b)²=a²+2ab+b²

(4+6p)²=(4)²+2(4)(6p)+(6p)²

(4+6p)²=16+48p+36p²
